Open Question

The air conditioner on my 2006 trailblazer doesn't work

The air conditioner on my 2006 trailblazer only works when the outside temp is under 60 degrees. When it heats up outside, the fan blows hot air... and the fan never blows hard, even when turned all the way up.

SOURCE: No ac

The ambient air temperature sensor is bad or has a connection/wiring problem. It is not blowing cold air because it thinks the outside air is less then 35degrees. When the computer sees outside air less than 35 it disables AC so that ice will not form inside the vehicle and in HVAC system. The sensor is directly behind the front grill. You might be able to check it for connection/corrosion/frayed or damaged wires. If no evidence of this I would replace it.

What temp should a/c be in 1995 chev on max


Hard to say.
Under normal conditions, vent temp should be about 20 or 25 degrees less than outside air temp.
So if outside air temp is 90 degrees and the engine is at idle speed, vent temp would be around 65 or 70. On the road the vent temp could be less than 60 degrees.
If outside air temp is 70 degrees vent temp will be around 40 - 50.

Why 2006 Chevy Trailblazer air conditioner blower does not blow


Theres a module inside the blower housing that seems to be a problem on these vehicles. Mine wouldn't blow on 5. Took it apart and discovered it to be a bad connection where this module plugs into the harness or something in the module itself shorted as one of the pins looked as if it had been hot and the plastic around it was melted. Theres 2 different parts available, one is about $60 and the other is $25. Get the higher one because its the newer designed part that wont fail.

Need help with an idle problem on a 2006 trailblazer


The belt should be on an automatic tensioner ,your problem is not in the belt but it is possible you have air in the coolant system and the coolant sensor is not submerged and therefore will not allow engine to reach maximum rpm's,try running engine up to temp while the coolant cap is off and wait for all air to come to surface.that should solve you problem. good luck.

Temperature control sensor?


Sounds like a loose connection -38 is probably the open circuit position. Not sure where the sensor would be though.
