No heat out of the defroster or floor positions. Could the codes P0171, 0174, 0401, 0303, 0301 and 0302Pending cause this problem?? I read the no vacuum to contoler should create a defroster mode only. I plan on doing the isolator bolt seals and cleaning of the egr ports.

I have not had a chance to look for bad or disconnected vacuum lines yet.

Any suggestions would be great

thanks
