89 Dodge B150 ac/ heater problems - October 28th 2020 12:40 am
I purchased this van not knowing a squirrel had chewed through the heater box near the fan housing.
They made nest in both inner fenders , I cleaned everything up , replaced heater core, replaced fan relay behind glove box.
Repaired the hole .
Now when I move the selector lever to A/C (left)the heater and defrost blow hot air from outside fan. If I move the lever to heat or defrost (right) the inside fan turns on and blows cold air.
This has been a frustrating endeavor. It seems to be backwards .
I could really use some Hvac diagrams my Haynes Manuel isn’t specific enough.
And the passenger side defrost doesn’t seem to blow very much . Could be a blockage?
Any help is appreciated.
No squirrels were harmed but they have prejudiced my views about them.
