Honda - Accord :: Heater Suddenly Blow Ice Cold Air And Odd Shaking Routine
Jan 3, 2012
2005 Honda Accord.
Problem 1: Now that is is finally getting below freezing and I am having to use my heat, and I have noticed that it will all of a sudden blow ice cold air. It does not matter if I am idle / accelerating / decelerating. I must provide a disclaimer... I have not had to use the heat in the car since I purchased it Certified Used from the dealer in South Florida. After moving back to where it actually gets cold I find this issue. I had my trusty mechanic look at it and he flushed the heater core. That is problem 1.
Problem 2: For about 6 months now my car has been doing this odd shaking routine. It happens probably every time I am out driving. When it starts to shake, I can prevent it from dying by revving the engine. It does not matter if I have just started the car, am sitting at idle or if I am driving down the road. No check engine light or malfunction indicator light has come on the entire time. It feels like the car just runs hard, not nice and smooth like it used to. I have brought my car in to the trusty mechanic three times now and he can not find any problems. I did notice this morning that while sitting idle at the stop light, my car had its little epileptic shake and then stopped and the RPM's dropped to 500.
Later when I arrived at my destination, while sitting at idle before getting out of the car, the RPM's were at 2000. I have routinely put in fuel injector cleaner additive when I fill up with gas... maybe once a month. I usually fill up with regular gas, but will occasionally fill up with premium. This whole situation is blowing my mind!

I have a 94 ford Taurus all of a sudden my ac doesn't blow cold and my heat doesn't blow hot. Also every now and again I hear a sound like an alarm clock coming from passenger side??

I can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.

I have owned my 2008 Rx 400 h for just over two months now and at the risk of sounding dense, am I right in assuming that when you are coasting along without the engine running, the heater will start to blow cold air? Everything works fine until you lift your foot off the pedal. This is my first Lexus/Toyota and hybrid so I'm not totally au fait with how it should be working.

My 99 grand cherokee's heater is broken - fan blows but only cold air. I've had two mechanics tell me its probably the blend doors and will be quite expensive to repair because it requires removal of dashboard. Looking for after market repair kit which allows for a DIY fix going through the glove box? Is this a good bet to try?

Cannot figure out how to get the heated air to flow through the back via the rear vents. All I get is outside air. I cannot find anything about it in the manual. The dealer has no clue but is trying to find something on it. New 2009 Santa Fe Limited.

So the heater on my 2001 f150 will only blow through cold air. I thought that I may have a heater core clog so I back flushed it with water until it was coming through clean and unrestricted but that didn't solve the problem.
Now, some things to note are a potential coolant leak. I can't seem to find one but I filled up the antifreeze about two months ago and when I checked it the other day it was more or less empty. I've filled it up again and I will monitor it for the next couple of days.
Another thing to mention is that no matter what setting I have the heater on (ie 'panel' or 'defrost') I get cold air blowing at the passenger side's feet. Is this indicative of a hose leak or something?
Also worth noting is that the intake hose to the heater core gets hot after driving but the outtake stays cool. This is why I originally thought I had a core clog.
Should I be checking my blend door? If so how to I access it?

Like a good boy scout, last week I changed the engine air and cabin filters in my 59K-mile 2007 Honda Accord.
Taking out the air filter, I saw the usual insects and dust in the housing and got out the shopvac to suck them out. But the hose was on the wrong port, and I ended up blowing the insects and dust everywhere. Augghhh! Into the intake manifold for sure, I'd bet. I connected the hose right, put it to the air intake, and prayed I was vacuuming all the dust I'd just blown in.
The next day, on the way to college, the car ran perfectly the first three miles. Then, a half mile from campus, the check engine light came on and the car began running badly. RPMs wouldn't increase even if the gas pedal was pressed. The speed couldn't be made to go above about 20 mph. The transmission, ordinarily smooth as silk, now clunked. Fortunately, I was able to reach the college parking lot. I parked the car and went to class, hoping the car would fix itself while I was gone.
Apparently it did. After the three hours I was in classes, the car started up just fine, and it drove home just fine. Except that the check engine light was still on.
At home, I used my OBD2 checker (bought five years ago but never until now even taken out of its packaging; love my Accord), saw a fault of P2101, and erased it. That made the check engine light go out. P2101 has to do with air/fuel, so it must be related to the air filter fiasco of yesterday.
By the way, there's a rattle from the glove compartment (which is lowered to replace the cabin filter). When the compartment door is open, the rattle goes away. Will troubleshoot this later. Am more concerned with being certain the check engine light doesn't come back. I don't want to go into limp mode on the highway, hours from home.
Two days later, I took advantage of a Sunday afternoon to try to blow/clean out the injectors and intake manifold. I put in a bottle of Techron and drove the car 45 miles, mostly on a nearby semi-rural highway. It has a 70 mph speed limit but at times traffic was doing 80. (Texas.) The car ran perfectly, both highway and city.

I took my 200000 mile Prius to a garage that is highly recommended and the mechanic stated that I need a new evaporator and expansion valve. He tested the car for a day. There was no time to do the fix so I arranged for a dealership that I trust to do the job. When they were ready to do the work, they detected no leak in the evaporator, but said that the compressor, expansion valve, and AC line needed replacement. (They showed me the leak in the compressor with special glasses.) After I called the first mechanic with the new info, he said that he could detect a leak nowhere, but, in the evaporator, and, at the expansion valve area. I am now stymied as to what I should do.

Push A/C button is always on green. The (air speed) 01234 button is also always on green. the Push button turns on and off orange whenever I click it.
Anyways, the AC doesn't blow any hot air... always just cold. I've adjusted the dial to red and have left it there for a long time... no hot air. Any trouble shooting I can do?

Here's what I have. 02 X 7.3L 4x4.
Heater will work fine. Then out of nowhere just blow cold. I can turn it off then back on it'll blow hot for 1 minute or 20 minutes. Then out of nowhere blow cold again. It doesn't matter if I'm highway driving or city driving.
I'm kinda thinking it may be the door in the duct that's just closing. I real don't know.

99 Accord, 160,000, automatic, 4cyl vtec, properly maintained.
Recently the CEL came on following an episode of the engine running poorly. It painted EGR code P0401 which is being dealt with, and, P1739: "third clutch pressure switch circuit fault." I investigated briefly in my Haynes and found that P1739 is one of the codes that will not trip the CEL.
I have not had any major issues with this transaxle. The fluid is at its proper level, Honda Z1 brand, and in good shape. I have it changed every 20,000 miles. Sometimes if I am driving along in 2nd gear, right around the upper speed limit before it would shift to third (20-25 mph), the car will jerk just a little but it is driveable. Could this be related?
Should I let this slide until something happens or should I get the to a transmission tech? What would you do? Could the thing go into limp mode one day without warning?

My 2000 F250 SD 5.4 AWD's A/C wouldn't blow cold suddenly the other day. I confirmed the A/C relay (engine compartment, 3rd down from firewall)was "clicking" but compressor clutch was obviously not engaging with dash switch on Max A/C and engine running. When I take of the 2 wire connector to compressor to see if it is getting power, the truck won't start..if I disconnect the A/C compressor plug while running, the engine similarly quits. I have never had another vehicle do this on me before..I could unplug the compressor on my Jeep GC, for instance, measure 12+ volts with A/C ON w/car running and no problem with Jeep engine turning off.
I have searched for A/C wiring schematic w/o success. I checked every fuse in cab/engine for continuity since I don't know which ones might deal with A/C..jumped hi/lo pressure switch connectors with engine running/A/C ON w/o compressor clutch engaging. Clutch turns easily, have banged it a few times, and air gap looks good. More bizarrerly, I hooked the compressor to a 12V/ground via its 2 male prongs and didn't get the clutch to engage.

I was driving home on the highway, and my 2006 Elantra did the following things in this exact order:
-Heater started to blow out ice cold air
-Temperature gauge rose, dropped down, and then rose right back up to the red area and stayed
-As I was slowing down to pull over, my tachometer dropped to 0rpm
-My "Check Engine" and "Battery" lights came on
-The car completely died and came to a rolling stop on the shoulder
I am trying to find answers as to what has happened to my car.

The dealer changed my oil last time and I checked it a few months ago and it was right at the top dot in the dipstick. I checked it again now and it is at a higher level, above the top dot by maybe about a quarter inch. The car is a 2011 honda accord with 15,000 miles on it. What's going on?

I have a honda accord 2003 ex. I bought the car over a year ago. A couple months in with the car i started to feel that the car vibrates while in idle. I replace the motor mounts and the shaking is still there. When i drive the car at night with the headlights on the shaking gets worse. If i put it in neutral sometimes there is no shaking and sometimes you can feel it a little bit. Also, in the summer when i turn on the ac the shaking gets so much worse, even if i put it in neutral the shaking is still pretty bad. One more thing, when i turn on the heat and put the car in neutral there is not too much shaking. I just don't know what to do anymore.

I recently purchased 4 brand new michelin tires. They are approximately 3 months old now. Beginning a couple weeks ago, my car started shaking profusely at 60mph when accelerating. When I let off the gas, it would stop. I went and got a tire balance thinking that was the problem... but it's still happening, and now it starts at about 55mph. I have no clicking sounds when turning the wheel, and my car runs great besides this! What this could be?

My 1990 Honda Accord just recently started sputtering and shaking a bit when I reach 1500 rpms, if I'm under that she's fine and if I accelerate passed that she is fine.

My car shakes when I start the engine, and continues to shake, it doesn't matter what gear I'm in. It also smells like gas when I get out of the car. Since my check engine light is blinking, and with all I've heard on the show, next step is to to take it to a mechanic. My question is, would it be okay to drive it 5 miles to a mechanic, or should I have it towed? Someone said it may be a misfire, and to change the spark plugs?

I drive a 97 Honda Accord and just recently started experiencing an issue where while driving, my ignition suddenly shuts off. Sometimes when this happens I'm able to turn the key and get the ignition started right back up while coasting, but usually forces me to coast to the side of the road instead to throw it in park and restart ignition (instantly, no sputtering). This problem seems to occur most frequently while driving at low speeds or stopped at a light or sign. Despite the ignition cutting, my headlights and radio, etc remain on leading me to believe that the battery is fine. I've taken it in to get it diagnosed at two different mechanics so far but they've been unable to replicate the situation and couldn't do anything. The problem is occurring more and more frequently (as much as 4 times for a 10 minute drive last night) and I'm going crazy trying to figure this out. Anything similar seen before? (spark plugs, alternator, blocked air filter, etc?).

I have a 4cl- 2000 Honda Accord about 160,000 miles on it. I have been having a shaking problem with my engine when it starts up after warm. If I drive more then 20 minutes, stop my car, to say go run an errand, and then come back and turn it on, it shakes and sometimes stalls out. I notice that the RPMs don't go above 1000 and waiver below that. When I do get it going, I have to tap on the gas a bit to get it to regulate. On longer drives after I stop it, it won't start and have to leave it sit for about 20 min. and then get it started by tapping the gas.
The check engine light that did come on has been checked as a cylinder 2 misfire. Sometimes it will flash and sometimes it will not come on.
I have new wires and spark plugs. A 3 year old timing belt. No vacuum leaks or gas line leaks. (all been checked by a mechanic).
