#737 of 1888 1997 Jeep Wrangler Heating Issue
Feb 25, 2007 (7:12 pm)
I've got a 97 Wrangler Sport with 81000 miles and I have a heating issue. The fan only runs when I have it on high, when it is on any of the three lower settings it will not run, but some air is being blown out of the ducts. It does the same if I'm trying to heat, cool, or use the A/C with the fan - it still only runs on high. Any suggestions?

While it's possible that you may have a faulty switch or bad wiring, it's much more likely that the resistor pack is at fault.
The resistors are used to control the lower three speeds and the pack is located in one of the HVAC ducts, accessible in the passenger footwell.

It's always good to hear when it works out.
P.S. The check is in the mail.

When is the last time you changed the spark plugs or wires?
Check your distributor cap and make sure the contacts are clean as well. Have you checked the OBDII codes to see if anything is being thrown?
Sounds similar to problems I had before my throttle position sensor went out last year. But check the plugs, wires, distributor.

Can you you drive through this spluttering to reach higher rpm, or are you held at 3K?

Probably the heater switch is burned out...
This part is cheep but is only a symptom of a much worse problem.
There was a recall for a faulty heater, dash ground.
This caused the switches to burn out, wiring to overheat, motors to smoke and other electrical issues.
Check with Jeep and see if your Jeep is included in this recall.
The recall was for a limited number of vehicles.
The problem is wide spread. "DENIAL"
Have the blower motor and all heater/ac related electronics checked.
The best solution probably is to replace the heater/air conditioner console, (This is the fan switch, heat/ac selector switch, temp mixer) all damaged wiring.
Make sure the ground wire is firmly attached and undamaged.
The wiring harness for the heater/ac is not available so it will need to be repaired. (Go figger that one)
When you are done write a letter to Dodge and ask to join the frat.
This has been a problem on Dodge vans since 1973.
(Keeps the service bays full)
"Thank you Sir. May I have another?"
Maybe someday Jeep will again be come its own company.
