2003 envoy xl blower problems

the rear vents only blow cold air the front vents dont blow as hard as usual and sometimes will not blow at all.dont want huge labour cost just to find poroblem.any ideas would be appreciated.thanks

well i have it booked in the garage to get the blower motor changed.hopefully that is the problem and it's not throwing money away.

Have them check the blower speed control/relay first.

I'm having a similar problem with my rear blower (reflow)... It will not go off unless I disconnect the battery.... Plus it keeps draining my battery so I don't have no other choice.... What can the problem be?

Same advice, locate the blower relay, I assume this is the rear a/c system? Not sure where that one is located, but for the ft unit it is behind the glove box on the blower case.

Yes this is the rear a/c system.... Do you have any idea where the relay is?

I would look near the rear blower housing.

I have a similar problem when I sometimes have cold air blowing on the drivers side and hot air on the passenger side. I keep turing the temp know from cold to hot and eventually it starts blowing hot air on both sides. Anyone have a better solution?
