Time to do the dreaded heater core change, I got a new ford unit, somone had told me to change the a/c evap core while i was in the hvac box, is this a wise move?? My car is a 91 model.
I would change anything i could while i was doing it. Its a PIA. I got mine done in 4.5 hours including rerouting my tach wires. I was told that it will take 8 - 9 hours.
