In the morning when 1st starting the car, the climate control does not work


If the climate control is on "auto" there is a delay before starting. For 15 minutes it is either freezing cold outside or needs repair. Depending where you live. Well anyway a way around the delay is to go to a manual setting and the system should start blowing right away.

Of course if it hasn't warmed up yet the air will be cold!!

Track the temperature gauge on the dash. As the temperature lift's off and approaches normal range heat should be coming from the vents,

New cars that are super efficient are very slow to heat up. The old gas gushers had plenty of heat to spare

So if you think it is cold where you live heck out the videos,

NO HEAT. A/C works fine. Air blows but no warmth. blows cold air for front defog and cold air blows when temp cranked high 1-5


warmth comes from the heater in the car
if it is climate control check the climate control module
check for heater control in the vent settings as the hot water tap may not be turning on

Chevy 2005 tahoe z71 blows cold air in back but hot air in front


Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).

The fix:
Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process.
In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.

If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.

Good luck.

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?

My ac was working fine then one day it stopped and now only hot air blows out the mechanic said the ac is fine and works good but there is a vent door that switches the ac to heater and he said it was...


There is a blender that controls the air flow to go through the heater core for heat, and the evaporator for AC. It very well could be stuck.

You maybe able to try and get it to get unstuck by running the cars AC and switching from heat to AC back and forth and see if it gets unstuck. Just turn it on full blast and go from heat to cool.

If that fails, then you may need to service it. There should be a Lever Marked VENT under the dash, usually by the Brake and other pedals on the Driver's Side. Close the VENT and that will stop the Air from coming in and leave the A/C Blowing through the outlets(Vents).

I also read this online if you have an electronic climate control. "On climate control press off and heat button and let go quickly. Then press automatic. The display will start rotating eventually displaying a code 025,125 , 024 etc. Then press defrost to stop. You may hear blend door operating atb that time. It worked for my climate control."

make sure you dont have a vacuum line off under the hood, going into the firewall, or to a control valve that shuts off the hot water to the heater
