Spokes Posted January 29, 2009 Share Posted January 29, 2009 hey guys i just found out about this site and after reading for a while i desided to sign up! well ive got a 1990 comanche long bed. i got it back in december as my first car! (well jeep) but i love it so far but the heat in it sucks! it will blow semi warm out the defrost and sometimes semi warm out the floor but usually not, maybe 5degrees warmer than it is outside. so i freeze. i was wondering what i can do to fix this? the flapper valve is working and the heater core seems to be ok. and i don't see any vacuum lines off. my dad and i are stumbed. thanks! here is a pic of my MJ! :brows: Link to comment Share on other sites More sharing options...

jtdesigns Posted January 29, 2009 Share Posted January 29, 2009 Get a thermo from the dealer,, then flush your coolant system,, including the hear core.. Link to comment Share on other sites More sharing options...
Spokes Posted January 29, 2009 Author Share Posted January 29, 2009 sorry i forgot to say we replaced it, it had a 165 in it we put a 195 in it. that helped a little, so change out the heater core? Link to comment Share on other sites More sharing options...
