92 jeep cherokee xj laredo. the heat doesn't work, if anyone could help me try to fix it that would be awesome, already checked the fuse and thats not it. help me out please. im a rookie so try to describe it as best you can to someone that doesn't know much.

 

Bad heater core or clogged heater core.

 

it doesn't blow at all, or it doesn't blow hot?

 

If it doesnt blow at all and there is some hot air coming out it's most likely the blower motor on the passenger side of the firewall. If it's blowing but not hot its probably the heater core.

 

it doesn't blow at all, even cold air. tried replacing the fuse and it already blew.

 

It doesn't blow at all so its probably the blower motor and not the fuse...

 

cool, thanks guys. should i just go to the junkyard and get one there or is there somewhere i can get a new one?

 

you kinda have to get a new one. a blower motor isn't something i would get from a junkyard.
besides, first check the harness for current, if there is voltage going to the motor, then replace it.
the blower motor in my '97 is going out, and so far i have been very successful getting it to work by tapping it with a wrench through the passenger floorboard area.

 

Definitely check for current in the wires.
I wouldn't buy a used blower from a JY. Just get a new one.
I just replaced the blower and resistor in my 97 after fighting with it for 2 winters.

Tural- My 4 seasons blower is still quiet after a couple months of hard use.

 

i hear ya buddy. gotta get one soon, but i figured i'd "wrench" it until the weather warms up and money falls into place. don't wanna freeze my fingers to get heat going.

 

consider taking it in! weigh the cost and aggravation of hit & miss trial and error
