Buick Rendezvous 2002, The heat gets hot, and the air gets cold but it barely blows out. Its sounds like the blower is working fine. But the air blowing out is not very strong

just one idea my freinds buick if it gets low on antifreeze it will not blow hot air maybe you can check the antifreeze level

SOURCE: Only cold air on passenger side

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.

hi press. switch on compressor could cause problem - there is a service bulletin for this - i will be testing a 2003 buick tommorow for this problem

SOURCE: 2002 rendezvous blower motor barely blows

if its roaring reallly loud with the fan on high you might have a plugged cabin air filter,its behind the glove box,you should be able to pick one up at a local parts store,hope this helps

Sounds like you may have a stuck or broken blend door, could be your controls as well. Have you tried different settings (i.e. floor, front, floor+front)?
