Sierra :: 04 GMC Heater Would Not Blow Any Warm Air Until Vehicle Moving
I have a 2004 gmc sierra and it is having heater issues. For a while now when starting it up cold it would not blow any warm air until the vehicle is moving. The other day while driving it would go back and forth between hot and cold.

I have a 2004 Santa Fe and have recently noticed the following problem. When it is hot outside (95 degrees) and car has been idling for a while, suddenly the A/C will start blowing warm air and the temperature gauge will start creeping up above normal. It hasn't fully overheated as when this occurs, I shut off the A/C or start moving and it returns to normal temperature. The A/C will then work properly again. Also, when this happens, if I turn the car off and then try to start it again a few minutes later, it is very hard to start but eventually starts. It can easily be reproduced, but I want to try to understand possible cause before taking it to a dealer. I was thinking maybe fan going bad, or fan switch.

When first starting a 2012 Sante Fe GLS with standard AC each morning, the vents blow warm for up to 3-5 minutes and therafter are fine. Additional starts for the remainder of the day seem fine. We live in a hot climate, but our 2011 Sonata, which is parked in the same garage, does not have this problem. No unusual soundsor lack of air circulation, and after 5 minutes it spontaneously starts to blow cool air. Problem began 2 months after purchase.

It does blow warm air, but never gets hot...can't keep up with single digit temps. Every thing looks to be operating properly...
Intrepid :: 98 - Heater Will Not Blow Hot Air When Idling (just Warm)
I am having a problem with the heater on my 98 2.7 Intrepid. Will not blow hot air when idling (just warm). After several minutes of driving with heat on air temp goes from hot to warm. It might just be me, but it seems like the air flow is cooler coming out of the defrost vents than from the dash/floor vents. Thermostat has been replaced (proper operation verified before installing). Had to replace gooseneck and heater coil supply tubing due to a leaking bleed valve. There appears to be NO air in the system.
Heater core was backflushed, there appears to be no restriction. Hose temp on exit line is approx. 15 deg. cooler than supply line when fan is running. Blend door actuator was replaced last spring (motor shorted). When temp control is moved from hot to cold temp changes drastically and door can be heard moving. On-board ATC diagnostics indicate all is good. Engine is running at normal operating temperature, not overheating or running cold. Is there a cabin filter or inlet supply for the air that could possibly be obstructed? Air flow seems adequate, not restricted. AC works fine.
Suburban :: 2000 - Heater Blow Warm But Not Hot Air
I have a 2000 suburban with a 1500 motor and 300000 miles. Last year I replace the water pump and the thermostat. The heater would blow warm but not hot . But only when I start to drive. Yesterday I decide to change thermostat again thinking the new one from last year was faulty. Now the heater only blows cold air .

My heater quit blowing hot or warm air all of the sudden. I took my mechanic and they said it showed no codes and were afraid to mess with it so I took it to a dealership. They worked on it most of a day. Said nothing showed a code as bad, they got into it and found the air going into the heater core was hot, but it was cool coming out. They spent some time flushing the coolant and said they found some sediment in the coolant fluid. They were hoping to flush out anything clogging the heater core.

View 6 RepliesCavalier :: Air Conditioner Suddenly Blow Warm Or Even Hot Air At Idle
I am in need of the diagnosis of an air conditioner & radiator fan problem on a 2002 Cavalier LS Sport.
The air conditioner blows cold air while the car is moving most of the time. At idle, the air conditioner will suddenly blow warm or even hot air.
At idle with the air conditioner off, the car idles fine. When you turn the a/c on, it runs a bit sluggish. Also, ever 5 seconds you hear what I assume to be the compressor cycle on/off.
After a little research I discovered that this problem could be a faulty radiator fan motor.
Tonight, I pulled the electrical plug to the fan and found that I had voltage to the plug when the engine was running with the air on or off. I then ran wires direct from the battery to the fan and could not get the fan to spin. This obviously tells me that the fan motor must be bad.
My real question is.....should I really have voltage to the fan when the a/c is off and the car is just started? I thought the fan should only turn on when the engine got warm with the a/c off. I started the car and pulled it in to the garage and then shut it off before I did my testing so I don't think that would classify as getting the engine warm.
I am now wondering if the voltage was always present even with the AC button off because I may have had the fan in the recirculate mode. The AC light is lit in this mode even when the AC button is off.

I have a 2000 Isuzu Rodeo with 230,000 miles. The A/C is cold when first turned on after start up, warm or cold engine. After about 5-8 minutes running on a sunny day, driving or at a stop, it starts blowing warm. If I shut the A/C off and leave it off for 30-45 seconds, it will blow cold again. On an overcast day it will blow cold for 15 minutes or more.

View 10 RepliesFord 6.0L Power Stroke Diesel :: A/C Blow Cool For A While And Then Go Luke Warm
Just went on a trip to SC. It was hot as hell - 100F most of the trip. The a/c would blow cool (not exactly cold) for a while and then go luke warm (way better than outside but not particularly refreshing) for a while. So I was reasonably comfortable but definitely not cold.
This would happen about every 15-30min where I felt like the compressor had stopped working for a while. I am thinking the compressor is probably limping along and about to die. Usually I thought these things just up and die though. Clogged accumulator? IDK - nothing has been done to the a/c system since 2009 head gaskets.

I drove my 1998 VW passat to work last week, a day after changing spark plugs, fuel and oil filter, and engine oil. After work, the car refused to spark. Had to leave it overnight. Till today, the vehicle has refused to spark even though my electricians keep telling everything seems to be ok. The latest I was told was that the engine has lost pressure. What does that mean and what is the possible remedy?
View 4 RepliesPrius (Gen 3) :: Using Remote AC Button To Warm Up The Vehicle?
this is my third hybrid (Camry hybrid and RX 400).
I have a '11 Prius IV with solar panel and remote AC button on my fob. Not much good information on this in the manual. I'd like to use the remote AC button (assuming a charged battery) to begin the interior warmup and defrost process on cold mornings.
However, it seems that when I hold the remote button on the fob as instructed in the guide, it turns everything on in the car for a brief moment (5 seconds or less) as opposed to a full 3 minutes as the manual describes. Again, the battery is at least 3/4 to a full charge and the process begins when I hold down remote start, but it just turns everything of after a brief period.
