1994 jeep xj with 4.0 motor - Ac/heater fan only blows on low and medium speeds.
There may be previous post on the cure for this but I did not find one. Any thoughts on this?
Thanks

I thought I responded to this. There are two things to check. First is the switch in the HVAC selector in the dash. They can easily get cooked and loose a terminal or wire connection. The other is the ballast resistor located on the HVAC housing under the glove box. They can get hot too and get fried

I'll check them - thanks.
The resistor looks fine - now I need to sort out how to get to the switch.
You will have to pull the bezel

Yes, the bezel came out easily once I sorted out process. The switch is burnt along with the plastic connector. I have a new switch coming today from O'Reily's about 17.99
Glad you found it. That is usually the case when you loose hi speed

Thanks for the info - the switch is replaced and all works great.
