My air conditioner blows cool air (not cold) when I am driving, and when I am stopped, it is warm air. I had to replace the sensor last year. Could it be that again, or something else? Chevy Tahoe 2003 ..
View 2 RepliesMy 2007 Prius air conditioner blows mainly warm rather than cool air. I took it in for repairs and they replaced the high pressure hose but it is still not cooling the car. The dealer has had the car for 2 weeks trying to determine what the problem is. They tell me it should be blowing 42 degrees but is only blowing 62 degrees. They think that it might be the invertor that cost $1,000.
View 1 Replies98 Tahoe ac giving me warm air once again. 5 weeks ago had it in the garage. they found a leaking schrader valve and re-charged and added dye. checked it and didn't see anymore leaks. they said keep an eye on it and if it stops cooling bring it back. well.........it's going back! it's blowing warm air even though I hear the compressor kick on. what else could be giving me problems? of course i'll take it back but i'm just wondering if a switch failed this time or what the heck is happening. I was surprised to hear the compressor running with warm air.
View 14 RepliesDecided to put the AC on one day but nothing but warm air, observed compressor didn't cycle. Why this would suddenly occur and why?
Vehicle is a 98 tahoe.
Pulled up to subway today and hit the switch to put the window down for my order. paid the lady got my order hit the switch but the window went half way up and stopped! drove off and tried to make it go down or up, nothing! tried again in a couple of minutes then it went up. I haven't done anything since. Am I looking at a huge repair? Never had a problem before.
View 4 RepliesI have a 2004 Z71 Chevy Tahoe with 192,000 miles that runs great. The issue I have though is the electrical system is going haywire (no pun intended). The front A/C and heater stopped responding to the level knob, therefore doesn’t blow, the dash lights will periodically dim and go off, the horn doesn't work when I want it to, and the A/C would sometimes blow warm air when it did work. The A/C used to work on all levels of the dial, and then over time, level by level, they stopped working; however, the back blower works well on both A/C and heater, which is operated by the overhead control knob. I open the front vents to allow outside air in, rather than recirculated air, and the air coming out of the vents is A/C air, but it only blows when I'm driving of course.

View 2 RepliesI have an '04 chevy tahoe, only 70k. Very recently the front end of the car has started to shutter while driving. This happens when I am going generally above 45mph- more so going up a hill. It feels a little bit like I am driving over unevenness/ripples in the road- even when it's smooth flat pavement. When I take my foot off the accelerator and just coast the vibration stops. I got new tires put on front so it is not a wheel balance issue. The car does not pull left or right either like out of alignment. And the engine rmp's do not fluctuate/strain when the shuttering starts.
View 5 Replies1) no cool air at all from AC
2) low pressure side shows 0 even after adding some refrigerant
3) ac compressor engages. I can hear a slight load on the motor when I push the ac button
4) when pressing the ac button the fans don't automatically come on. They should come on right
I have an '08 350 with less than 82K miles. My problem is the AC. The vents on the passenger side blow out cool air and all the vents on the driver's side blow out hot air. Even the vents in the backseat, the left one blows hot air and the right one blows cool (my son informed me of this as I hadn't even checked). As you can imagine it's very uncomfortable driving around in this CA heat every day, especially since the driver side vent in the center cannot be completely closed. What could cause this?
View 1 RepliesI have a 2004 Buick Century with about 48,000 miles on it..the A/C blows very cool but not cold,it should be colder..i also have a 2003 century that blows icy cold.. I hooked up a cheap gauge to the low side service port on both vehicles and got about the same reading. Other then being slightly low on refrigerant is their anything else that would cause the A/C to blow cool air rather then icy cold? The compressors seem to kick on the same on both vehicles. I really don't want to add refrigerant if it's not low...
View 4 RepliesI have an '02 Durango, and the AC only blows cool air when going down the road at 25+ mph. I thought I'd try putting some refrigerant in, but when I hooked up the gauge on the can it buried the needle, so it's over 100 psi on the low side, and the pressure was high enough that no refrigerant would flow in. Up where the lines attach to the expansion valve, when idling the in line is HOT - like too hot to keep your hand on and the out line is about air temp. The guy at the parts store thought the expansion valve was bad. As stated, AC works okay (but not excellently) while going down the road.
View 6 RepliesI've read that this is a somewhat common problem but can't find the part number to what I need. My heat stopped working and won't change blowing any temp only blows slightly chilled air. I found that its suppose to be a part in the dash that controls this thru the climatronic head unit some lever that isn't getting pushed over correctly dew to a worn out part. What part I need to get my heat back working.
View 4 RepliesMy 94 is on the mend , since I got it a few months ago. The air conditioner blows cool , just not cold . It's still a R12 system, and I got the fittings/R134a/oil charge/and mineral spirits to do the change over, but hesitated when I found someone locally had a few cans of R12 for sale . My thought is to buy 1 can , and see if a shot would make the difference before going through the procedure to flush the 12 out and go with the 134a .
My biggest problem is lack of a gauge set , but a guy from CraigsList here says he walk me through the change over for 60 , and betting he'd have the hoses for a 12 system to hit that if that's how I decide to try first. I just wonder why , since I got it , the "cool" it does blow hasn't changed so I am betting it isn't leaking , but the jackleg I got it from was one that IMHO wouldn't know how to open the hood , or what to leave alone, I am just at that point of impasse, as to which way to go ...
I took the dive into a new heater core, as the heater was not getting hot. These are the things I did while on my adventure.
1. Before reinstalling the hoses, I blew thru them to make sure of no clogs...water flew out the other hose..no problem..no clog.
2. inspected mix door not cracked or broken...no problem
3.actuator opens and closes ok, I assume, I can hear the motor run and the door thump closed...no problem
4. water and anti freeze level good....no problem
Start vehicle,let warm up, turn on heat.....No Heat...
5. check hoses at core, one is hot ,the other is not....Problem...
1997 f150 4x4 ...
I have a 1997 Camaro Z28 with 37,000 miles. A year ago it developed a problem of not starting after driving and being warmed up. The best description is when running errands, after the 2nd or 3rd stop, it will not start. If I let it sit for a couple of hours, then it will finally start, but I have to pump the accelerator to get it to start. If it sits overnight, it starts like a brand new car. When the problem happens, the starter is engaging and the engine is cranking. I have had a mechanic spend hours trying to diagnose this and has had no luck, partially due to the intermittent problem. The car is an automatic, not a six speed.
View 7 RepliesSo my heater works when I'm rolling down the highway. When I'm at about 20 mph or less it blows cool air. Also when it's just idling it blows cool air. What I might have an issue with?
View 6 RepliesYesterday the AC worked fine, until I got off work. Then it was blowing as usual, but almost warm air, it wasn't enough to cool the car. When driving and I turn it on, I do see the RPM's lower slightly. A co-worker looked at the compressor and clutch while I turned it on and he said they both are working. He did not see any bubbles in the little window on the line though. The light on the control button is not blinking and the in cabin filter isn't dirty.
View 2 RepliesI have a 99 Chevy Tahoe that the transmission keeps going out in. I've replaced the torque converter, cooler lines, computer. I've even added an additional cooler on the truck and it keeps burning three the transmissions.
View 3 RepliesTwo weeks ago A/C was slow to cool down on and blowing warm air for several minutes; works fine since then. One week ago, check engine light came on. At the dealership now, they say it the check engine light is for the clutch heater and this would also relate to problem with a/c not cooling properly. Waiting to hear what repairs will cost. Is this OK to continue driving? What exactly is going on? Does this part need to be replaced? Should we just tape over the icon on the instrument panel to avoid looking at the pesky light?
View 1 RepliesMy brother's truck is a 1997 , 5.7 L gas engine, fuel injected. 100k+ miles.
New plugs, wires, new rotor, coolant temp sensor & air filter & recent battery.
Started a few times after the new air filter & some dry gas & fuel injector cleaner & that was the last time it started.
Turns over but will not run! He needs this truck to tow a trailer to R/C boat shows (he makes parts for R/C racing boats).
