Question about 2003 Buick Rendezvous
I have an 03 Buick Rendezvous CXL with manual dual zone climate control and it was recently discovered that the passenger will only blow cold air. With both the driver and passenger side turned to hot, the passenger side blows cold air strongly while the driver side blows hot air weakly.
I would first check and make sure that you have enough Freon in the system, on climate control dual systems only one side will put out cold air if the system is low on Freon. Eventually, both sides will put out warm/hot air if the system continues to loose Freon. As with all leaks the system should be checked and then the leak causing component replaced/repaired.

I had the same problem this fall. They replaced the temp control module door. Luckily it was still covered by the extended warranty as it was over $700.

I would assume with multiple people having the same problems, there should be a service bulletin on this issue. may want to call dealer with vin # to verify. sounds like a heater control issue under the dash. something i would leave to the experts for repair
