I am a first time Jeep owner and this is my first post so be gentle with me
I have a December 2003 Jeep Wrangler 4.0l out here in the Middle East. Only had it for a few days and am slowly fixing the minor faults. One of those 'minor faults' is the AC blower. It seems to work but speeds up and slows down by itself.
A bit of a description.....
My AC temp and AC fan speed control sit by themselves under the steering column. Next to them in the bottom, centre of the dash I have heater and heater fan controls. If I set the heater control to 'defrost' or 'vent' I get the sound of the AC fan turning and cool air out of the centre vents. If I set the heater control to 'heat' I get the sound of another fan starting (both fans running now) and air out of foot vents. I can adjust the speed of this heater fan with the up/down switch on the left of the heater assembly.
I suppose my questions are.....
This sounds like I have a faulty AC fan. How do I get to it to change it?
As I never need the heater (never gets below 25degC out here) can I plumb the heater fan into the AC ducting so I get twice the throughput of air?
Is there a diagram of this setup anywhere for download? All I can find is a later configuration.
