3.9 V6.....Just changed my water pump.....while I was in there, I replaced hoses etc.....now my heater work. The blower works, but the air isn't hot. How should I troubleshoot this?

Thanks!

 

air in the heater core take off on of the hoses to the core top one and let some come out

 

they show the whole fan assembly to be the same part number for the 2.7 and 3.2 well it updated the part numbers u can get each motor and stuff seperate.

05072181AA motor left
05072180AA motor right
04758294 SHROUD
04758293 FAN - 2
P/N 04734648 NUT
FAN MODULE ASSY. P/N 04596402AA

 

Thanks for the reples.....got it to work now. Just manually engaged/disengaged the control valve a few times, and now I have hot air if I ever actually need it here in West Texas.....there's an abundance of that! Guess it was just sticking.

Thanks again!

 

i think i posted a wrong reply hehe

 

if you replaced the water pump and the heater no worky, then you gone and screwed it up bad!

1 = check that ALL wire harness are plugged in
2 = is the heater bypassed from before pump change
3 = is heater core clogged
4 = back flush coolin system properly.
