blower motor/heat problem help!

[sjohnston012]

i have an 06 gp and after a cold day i turned on the heat and blower motor wasnt working. the problem isnt the blower motor though. i had this problem about a month ago and replaced something and i forgot what it was. no matter what speed or where it is directed no air blowing. it does produce hot heat it just doesnt blow it out. help!

Sounds like a blend door

That would be the blower motor resistor.

I have the exact same problem. Works fine with the A/C just not with heat but still produces heat

I just had to replace the Blower Motor Resistor on my 04. I also had a bad connection at the power wire feeding the heater. If you pull the radio out, there is a junction connector behind it. Disconnect that connector, and see if any of the pins are burnt. The +12 pin on mine was burnt and not making a solid connection.
