SOURCE: 1996 Chevy Tahoe air conditioning not blowing cold air

That "thing" is part of the compressor clutch. When it’s spinning the clutch is engaged, when it stops the compressor is off. If it’s constantly cycling, you probably don’t have enough freon in the system. But remember, however the gas escaped before, it will escape again, unless you fix the leak.

SOURCE: 2005 chevy 2500hd duramax driver side vents blow hot air

It sounds like the HVAC head needs to be recalibrated, most likely when you unhooked the battteries you lost the memory to the control head, it's in a default position/state.

SOURCE: heater does not work on my 2005 chevy impala ls

If you car is coming to temp but you get nothing from the heater the first place to look is the coolant valve for the heater core. It is sometimes called a mixing control. See if the control is jammed or your control cable is frozen or disconnected from this valve.

The valve should be somewhere near the cooling lines leading into the heater core. I am sorry, but they may be under the dashboard as well.

Good luck and be careful.

2005 chevy trailblazer, why is air only blowing out of the defrost and feet panels? Not the front and no air blows on number 4 and 5


Some 2005 & 2006 GM pickups & trailblazers had a software issue with their climate control systems in which the HVAC door(s) which regulate each vent section, (including adequate heating and air conditioning) wouldn't operate as selected by the control knob. Originally this was taken care of under a repair bulletin put out by GM. You can notify your local dealership and check to see if the bulletin is still valid? If not, the dealer will update the software while checking for correct operation of the door regulators which in some cases was also an issue.

I have a 2004 Trailblazer and my rear a/c starts out blowing cold air but gets warm shortly after but the front a/c keeps blowing cold air all the time???? what could cause that ????


Just a little low on freon can make it get too cold and it freezs if you in position to check the freon level you'll find with the system on high and the engine reved up the low pressure is below 25PSI. fill it to reved up is above 25 and your problem will go away. Low on freon will make it cold enough to frezze up and then warm up as the air does'nt go though the ice. it'll work good as you start up till it frezzes and after it's stopped up with ice it blows warm (it's really too cold). the more freon in the system the warmer it'll all blow because all the pressures are higher and it's the difference in pressures that make it cold.

Have a 2002 Chevrolet Trailblazer that the air conditioning will blow cold on long trips but stops blowing cold air in stop/start traffic? A clicking sound is heard coming from under the dash when it...


It sounds like you maybe low on freon and your a\c compressor is kicking in and out at lower RPM's because of low pressure,then you build enough pressure to keep it running at higher RPM's.
