Any suggestions/answers would be greatly appreciated -
I have a 1996 Bonneville SE with 148,000 miles - suddenly I quit getting heat on the driver'* side - but lots of heat on the passenger side. We have changed the water pump, hoses, tstat, flushed the system, etc.. If we block off the vent on the dash on the passenger side I get heat on the drivers side - system keeps getting airbound and we can't find any problem anywhere.
We have checked with our local dealerships and nobody has ever heard of this happening, especially in the 3800 - This wouldn't be a problem except that winter is here for us (over 16 inches of snow yesterday!).
