Need some help!
Just replaced the heater core and what a job that was pulling the dash out.
Got it all back together and now when the hvac controls are in the cold position it blows hot and when is in the hot it blows cold. This is not a digital unit. I have done all resets that I have been able to find and ask about from pulling the all fuses, not touch the unit for 10 minutes for system to do a reset, took + and - off the battery for 10 minutes still the same out come.
Please any help would be great
