Our 1995 Cutlass Supreme (3.4 L engine) with electronic climate control is doing the following\
- If you manually select the upper level vents: the two vents on the right half of the dash pump always blow warm, the two vents on the left side of the dash alway blow cold. Makes no difference if the temperature is set for warm or cool.
- If you use the "automatic" climate control setting, air comes out of the floor vents but is never warm, even when the temperature is set for the hightest setting..
Any ideas on what is happening and how to fix it?.
I've got a feeling this will be an expensive dealer only repair, but I would appreciate your thoughts/advice Thanks in advance for any help.
