Heat not working, but can feel hot air coming out
I have a 92 YJ 4 Cyl. Recently the heat will not blow any air out on any speed. I can feel hot air coming through the vents once the car heats up, however again, I can not turn on the heat to blow the hot air into the car. What could be the problem?

does the fan even turn on? if not, maybe blower motor fuse?

keep in mind the heat will not come out the vents, it deactivates the blower. heater motor only works on "heat" or "defrost" setting.

Mine is doing the same... I check the fuse, think it was the right one, HEATER & FAN fuse under dash. Was fine...

Blower will not come on at all... Any suggestions?

the fan motor is cheap and easy to replace.
if your fuse is good .unplug the fan and run some wire from a 12volt post at the fuse box or from the battery and hook up the fan to see if it runs with direct voltage if it does check fan switch and or test for 12 volts with a multi meter .
if it does not start working with direct voltage to it the fan motor is bad and must me replaced or rebuilt .
