Hi. Only the driver side has a/c and warm air; passenger side blows cold air, then intermittently for a second it blows warm air, then cold again. When running a/c in summer, only a second of hot air, then just fresh air but no a/c. Wonder what can be wrong. A fuse? Looking for help.

I am having the same type problem, the difference is that the drivers side dash vents have cold and hot air, but passenger sid blows cold air when the heater is on, and the flow is directed thru dash vents. When A/C is on, cold air on drivers side, but hot air blows out of passenger side dash vents?

The Buick Dealership tell me they will a replace a diverter vale for $685. Oo? They said it was located under the glove compartment?
I dismantled the glove compartment, but I could not find anything that I thought was a diverter valve?
Hopefully we can get info on how to locate and replace the part.
