2001 Acura TL Climate Control Blowing only Cold Air.

You need to recharge the air conditioner. You can get a do it yourself kit for about 60 bucks. Works well and will explain how it is used pretty thoroughly for you.

not blowing air or when switch is on blows cold air when you have climate control knob turned over to heat? it could be a switch or blower motor or fuse if its not blowing any air. if its blows cold air when knob is on heat then is can be thermostat or low on coolant or it could be climate control module or it could be a air filter in dash.

If the front one is working fine, that means you have a flap actuator problem for the rear or bad therm device.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

Sounds like it's the climate control center that is bad. The display shouldn't change by itself.

Faulty air temp censor can cause climate control to do this.

Cheers Timo.

check your coolant level, and thermostat, if everything there checks out then it is probally a little door deep within your dash that swings open and closed with the temp settings on climate control, but if you a re low on anti freeze or your themostat is not working it will affect the temp of the air pushed out

replace the climat control.(over the radio on the dash).

you going to have to tear the dash apart (ac control panel) to see why your switch is not working. The control valve unit works on vacum systems and you need to find out where is leaking or the hoses is old and broke off. If your ac compessor still working and blowing cold air but does not adjust the temperature, it will be in the control valve. Is very easy to fix if you locate the leaks or a bad valves. hope that help some.

yes, very possible. but first check your fluid level, thermostat.
