95 Lesabre - When I hit a bump the hater starts blowing, I'll hit another bump and it will change to the a/c blowing, hit another bump and defrost wil start blowing. What's going on?
probably the selector switch , you'd have to trouble shoot it with a multi meter
I agree with "beatupchevy" something must be wrong with the HVCA controller itself for that to happen, try finding a used one at a salvage yard...... Other than that stop hitting bumps
Thanks for help. ( I'll avoid hitting any more bumps too.)
