Vacuum heater valve 91 GC
After living with lukewarm heater performance for too long with my 91
GC, I decided to get to the bottom of the problem. I found no vacuum
to the heater core control valve. The vacuum line goes into the
firewall to the under side of the dash somewhere. What is the
suggested way to start troubleshooting and taking things apart under
the dash? TIA.
