Hey I recently bought a 87 cherokee chief 4.0 manual.
When I got it there is no air coming through any of the vents(hot or cold) doesn't matter what settings it's at it doesn't blow air.
What do I check first? I tried some searching with no exact answer. I'm sure it's simple but have never had a renix before

 

Is it all going out the defroster vents?

If so, you have no vacuum to your heater control.

 

I have zero air. Any air that creeps through when it's on "vent" is somewhat cool.

 

Is the bower motor running?

 

Check the Blower motor resistor

 

If that was the issue, he would still have High blower operation but no others.

OP, you need to see if there's power at the blower motor. Got a test light or meter?

 

Confirm theres power as stated above if theres not main suspects switch in dash. If powers confirmed motor kaputz...can always give it a love tap see if it works....

 

Yeah. The old Fonzie fix!!

 

Aaa...Morning Sir...Showing our age here.

 

I do got a meter. I'll look further into it and report back

 

Correct. OUR age.

 

Jacks horse again....lol...
