how to disassemble dash to fix heater
my jeep only has warm air through driver side vents and not on passenger side or defrost. how can this problem be solved
Sounds like your blend door has broken and blocked the air from the other vents. I'd suggest having a mechanic or dealership do this -- I've seen a few done and you pretty much rip the entire dash out. At the very least, get a Haynes manual to help you, as it's not a quick and easy job.
