passenger side heater core...need help
I can smell anti-freeze coming out of the passenger side vents, truck has dual zone climate control, I have no warranty, I AM mechanically inclined, I am just looking for some tips on how to change this myself. Does the dash come out or is there access from below? Any suggestions would be greatly appreciated.
