View 3 Replies1998 Honda CRV ... Replaced the AC compressor. AC is cold only when the engine is revving above certain rpm. When at a stop, the air is warm...but if I put it into neutral and rev the engine to, let's say, 2000+ rpm, AC gets colder....or when I am driving, obviously. I know everyone is gonna say something about the condenser fan but would it be the fan given above circumstances?
View 16 RepliesWhen i turn my heater on, the ac come on instead. It does not matter what position any of the dials are on as soon as I turn the blower on the ac comes on. I do not see anything obviously wrong with the controls. All turn as they should nothing is striped. I have the 3 dial control setup no auto heater controls at all. and nothing is digital.
View 2 RepliesNot sure if it's transmission issues, on the road it took me to a neighbor city with no issues, but on my way back, while running it went from 70mph to 57-60mph and it won't let me go faster, it will not rev up more than 2000rpms, if i step further on the gas it will struggle to rev up, it will, but speed won't go faster, engine just had been rebuilt, it has no catalytic converters. I live in mexico, instead it has 2 "silencers" which were just installed as well since it was making a lot of noise through the exhaust.
Been driving it in the city, (no more than 35mph) with no problems at all, all gears feel great, but haven't tried to go up to 60mph again. Expedition XLT 1998 4x4 ....
My 98 expedition 5.4 starts fine the time but after it warms up it just cranks and cranks tell it finally starts.what might be the issue?
View 1 RepliesI don't know what it is but it comes on when the air is turned on inside the truck. Heat or A/C doesn't matter and its coming from rear passenger side by the window under the plastic molding. I thought it was a secondary blend door but as I know it the truck only has one.
View 1 RepliesMy daughters boyfriend was driving his 98 Expedition this evening and it died. From what he is telling me, he said it just all of a sudden lost power. As he was coasting to the side of the road, he said the RPMs where fluctuating then died. It cranks but won't start. No "theft" light flashing. All fuses under the hood are good. Turning the key, can not hear the fuel pump pressurizing.
No pressure at the Schroeder valve on the fuel line. While trouble shooting, found where someone had done a hack job of splicing the ground battery cable, wire was just folded over to hold together. As we were towing it home, they said there was a beeping coming from behind the glove box, which is where the PCM is I think. Kinda stuck on whether it could be PCM or fuel pump.
Today my 98 Expedition just started at 50 mph or 3000 rpm with battery light flickering and voltage fluctuation toward high end of 18 volts. Battery is 1 month old. No problems under 45 mph or 2500 rpm.

Here's the dumb question, if one bulb is out will that make the other three not work, something like the Christmas light strings?
View 4 RepliesMy Expedition started to shudder on a drive when I got it up to 55 MPH. I drove for about 15 minutes and parked well I drove it again and it started to do the same thing. Now the Service Engine Light came on. What the cause could be. (2000 Ford Expedition EB Ed. 5.4l Triton).

View 2 RepliesI have an 08 that the heater either works all hot or cold. It seems that when i try to control the temp it isnt consistent. It will be on hot, turned all the way the right in the red. Great, it gets too warm in the truck so turn it down a little. Then it is too cold. I only turned it down a little, not even in the blue zone yet. I turn it up a little and it is still cold. Turn it all the way up and it is too hot again. What is up with this. I hope it isnt the blend door syndrome. The truck only has 30,000 on it.
View 7 RepliesI have a 1996 Ranger that the Heater/AC blower only works when the outside air temp is above 45 degrees. I have replaced the relay, and the blower motor resistor. What could be causing this?
View 3 RepliesJust made it back from out of state hunting trip,driving to get new tires. And heard a bump sound , Driving about 40 mph and tack jumped from around 1800 rpm to 4500. Engine' smooth and parameters good . However will drive in low and 2 nd gear approximate 25 mph. When select drive will not shift into high without slipping an rapid rpm increase. Currently 135k service record's and general appearance were well maintained....
View 2 RepliesRecently my truck is only blowing heat or air conditioning on full blast in my 2004 Ford F-150 (New style, not heritage).
Level 1, 2, or 3 is exactly the same and blows almost nothing, then if I switch it to 4 it is full power.
I just don't know what exactly I will need to change. I know it would be a resistor pack somewhere that probably failed, I just don't know where it would be.
Do I just need a new control switch, or do I need a new heater fan?
2001 f350 blower motor for (A/C - Heater) works sometimes and sometimes does not.
View 5 RepliesAs the title says...The heater will only blow out hot air on setting 4. What could be problem before I take it to the dealership...
View 3 RepliesHeater works only on the passenger side, door,floor, defrost, dash. driver side blows out cold air from door, floor, defrost, dash. what would cause half the car to blow hot air and the other half to blow cold air?
View 2 RepliesI've noticed this winter that my Mazda 3's heater is barely working using fresh air. It definitely gives out warmer air than the outside temperature, but not by a whole lot. If I turn on air recirculation, then the air becomes appropriately warm. What would cause the heater to work one way and not the other?
View 3 RepliesFor the last week or so I noticed that my a/c wasnt working on the "1" setting, but the 2,3 and 4 settings worked fine. Last night leaving work, the blower was on the "3" setting and the blower suddenly just stopped blowing. I have cold air in max a/c mode only on 4, if I take it off of max a/c and just use the vents it will work intermittently on the 2 and 3 setting but never works on 1.
I know the 04-08 trucks had resister problems that would cause like symptoms, but I read somewhere that the entire system is different on these trucks. The truck has 4200 miles on it, so when I get off of work Wed off to the dealer it goes, I am just wondering what the problem might be for speculation purposes.
We have a 2010 Prius, and I can't remember if AUTO just works on AC. or is suppose to work for controlling heat also. (Doesn't seem to) Nothing in book, and search turns up nothing.
