i own a 2001 Chevy venture warner bro. edition. and the rear air blows hot while the air is on up front.. i had it checked out and the rear has no ac its just a fan for the back..go figure. my customized Chevy express full size van does the same thing
need Answerdid you fine out why this happens I got the samr problem The rear A/C has a heater blend door actuator that is stuck open to the heater core. I purchased one at Rockauto.com part #1572792.
I've got a better question, why is this question in the Chevy venture forum ?
The heater core is plugged. Blow it out with a compressor. If that does not work replace the heater core.
Most likely the rear expansion tube or valve is defective.
The back fan only works with the heating system. It only helps to blow around air when in cooling mode. In other words, it doesn't have a A/C coil like the front. Hope that helps
blow or blowsThey always blow out the candles.He never blows out the candles.
The 2002 Chevy Venture has a dual a/c system. The 2000 might also. There could be a hole in the hose that goes to the left and back of the van, but not in the one that is for the driver's side of the van.
Will blow.
At highway speed you can loose control and have a wreck, especially if a front tire blows out.
The air of your Chevy trailblazer 2004 blow out of the front vents when the air conditioner is on because the air condition is faulty and it needs repair.
If it still blows cold when it is at running temp, check the engine thermostat, its probably stuck in the open position.
