1997 Jeep Wrangler Q&A
I am assuming you mean the heater is not putting out hot air but the blower (fan) is working ok. First have the thermostat replaced then have the heater core flushed. If that don't do it, with the 4.0L engine, it's possible the water pump impeller is worn. Engine tempture in the normal range? Overheating, at all, on extended idle? (Sitting with engine idling for about 20 minutes) does the temp. gauge start to go up? Rev engine up after it's warm, does that help with the heater temp? If yes to any of those questions, have the cooling system flushed and water pump replaced! Verry common problems on this vehicle. - pushrod

Before this incident it would randomly turn off and take several tries to turn on again. After a few days it would cranak up with no problem.
I had my engine replaced a year ago and since then the A/C and heat do not work at all. Blower motor is fine, the A/C compressor does not kick in at all. Checked fuses and they are fine. Almost ...
...bought this jeep wrangler and found out nothing happens when the blower control is turned on ,no heat,no noise,nothing. All fuses check ok the relay checks ok, any body know whats going on?
