No heat on drivers side, but heat on passenger side.

I was wondering if anybody knows. My 1999 Pontiac Grand Prix is blowing only cold air on the drivers side, but it will blow hot and cold air on the passenger side. I was wondering were to look for possibly a hose off or something else. Thanks.

Thanks for the link Scottydoggs. This forum is really helpful!

no problem, been there my self. we all need to figure this one out sooner or later.

Any ideas on how much this part cost? And a good site for parts?

they aren't cheap, like 80 new.

junk yards are a good cheap option.

you can also take the old one off, turn the knob to hot or cold. what ever you need, and then turn the actuator to that setting to match, then slide it back on but leave it unplugged.

i did this for over a year, both sides lol
