I have a 98 C5 and the heater selector is very dim I need to replace once again, but the passanger side always has heat and drivers side has warm heat and the air selector does not send air wher it is directed. any ideas
well... on the airbox up under the passenger footwell where the blower motor is you have a manifold with multiple hoses connected to it that control the doors and such....I suspect something isn't working correctly ..see link
I have one from my 99....the whole damn thing but if you need one I could probably separate it....do some trouble shooting as suggested in the thread and go from there.....and yes its a bitch to remove that thing
its probably, most likely a simple fix....its tracking it down that can be time consuming
