Title: is my heater hot enough?!
Post by: KC on February 03, 2008, 10:05:14 PM

ok so i have a 91 YJ but i was wondering if my heater is working properly. right now if i start the jeep and warm it for like 20minutes the cab is still freezing and it never seems to warm up EVER! when i feel the ducts heat is coming through but its not completely HOT, is this normal for a 91?

No, I would check the coolant level and change the thermostat!

my money is on the heater core.  might be 17 years of clog in there.

Time to flush out your heater core, a lot of crud can accumulate there.
