If the AC is on Vent and it blows hot air in and the temp is at coolest. I think it does not matter because when you have it in vent it is venting air from the out side, it will start blowing air from the out side meaning if its hot out side the air will come out hot. Sometimes a car might blow hot air when you have it on full AC and cooldest. When you accelerate your car hard but it should cool down after you stop accelerating hard.
Your climate control in your 1998 Ford E250 Cargo Van blows cold air when in heat position and sometimes it blows warm air when in the cold position?
The heater control valve is bad. Sometimes the dual heater control valve will go and the AC will blow full heat.
control fuse blows when you plug thermostat to base controlling a gas pack unit
The control of vents on the Third Generation Camaro's is done with vaccum rather than via cable or electrical means. The problem is being caused by a vaccum leak either at the control unit or somewhere along the vaccum source line. Best check for leaks on both side of the firewall. Also, the control unit may need to be replaced. My Camaro had the exact same problem and it was a vacuum hose leak.
Depending on the atmospheric conditions, it sometimes blows from the north, sometimes from the south, sometimes from the east, and sometimes from the west.
2 thing's ambient temperature sensor malfunctioning if you have computer controlled a/c or heater a/c blend control actuator. I've seen both problems.
Prob the control switch. I have a similar problem with a 1993 Taurus. U put it on ac it blows out def. Def. blows out vent and none of it really blows out unless it's on high.
You either have a bad controller or a bad actuator.........
VENT TO HEATER CORE IS NOT CLOSING................
Which fuse is blowing - please be more specific as there are more than one fuse controlling many aspects of the car's electrical systems.
most likely cause is a bad ground or a short circuit, probably in the radio
You may or may not loose control and have a wreck. If you do not panic you will be ok.
Check coolant level Perhaps thermostat is not opening to allow coolant to circulate through engine and heater core
If your 03 Trailblazer blows heat out of the back vents when set on AC sometimes, it could be because of a faulty blower motor resistor block.
make sure both knobs are all the way up on red for heat...
Sometimes the fuel level meter is faulty... also the bulb sometimes blows on those things Mr X
Actually, the AC is always blowing cold air. Its just that sometimes your nerves can't feel it because your body is used to it.
At highway speed you can loose control and have a wreck, especially if a front tire blows out.
This may be a cause... My wife's 95 contour had to have the vacuum temp settings control unit replace 2 times. If you are constantly changing settings it really blows the valves in the climate control center... Just a thought.
There is no control group just variables like the amount of air and force that can go in each bubble
There's a malfunction somewhere. You need to have a shop perform a system performance test in order to properly diagnose the problem.
Yes, then you can control the robot and crash him into asteroids until the robot blows up
It may be due to the control head needing replaced
You have a short circuit that keeps blowing the fuse. Find and repair the short before putting a in new fuse.
Had same probllem on High. 2002 "The fan blows cannot control temperature via temperature knob on the dash?" Knob was useless. Turns out that the problem was the A/C/Heating control unit. Replaced under warranty $1000
