This is a chronic problem with Grand Cherokees. The blend doors inside the air box in the dash fail over time. This is caused by cheap plastic parts used by Chrysler that break easily.

Your problem is the forth Jeep I have seen like this in the past 2 months.

To check your climate control system for fault codes do this:

-Turn key to 'on'
-press and hold 'a/c' and 'recirc' buttons and turn drivers side temp knob clockwise one click.

Now the display will show 0 if no codes are present or one or more numbers if something is wrong.

You can check what these codes mean here: http://www.wjjeeps.com/climate.htm

My 1996 jeep grand cherokee is blowing cold air for the first 30 minutes of my ride home (20-degree weather), then warms up slightly but never gets hot -- i'm guessing heater core (it has 200k+ miles)


It is most likely a thermostat. As your car gets older the thermostat begins to lose its spring like properties and stays open all the time causing your car to never warm up.

If you can't tackle right away, start your car in the morning and let it run for about 15 minutes to warm up. Be sure to turn the heat on full blast and recirculate the air.

My Jeep Cherokee 95 Radiator temperature is always hot


100 degrees f? That is way too cold Either you have the wrong thermostat or it is wide open. 180 degrees is nominal and give you the best performance.. With AC on, expect 190 to 200 degrees. We are talking farhrnheit and not ccelsius, correct?

Rough, chugging when driving and conking out


Could also be a faulty mass air flow meter, or throttle position sensor. It's hard to tell, you need to take it to a shop to be properly diagnosed.

1995 Jeep Grand Cherokee chugs after it warms up. I've changed the fuel filter and it is still having the same issue. Could it be some sort of sensor?


Hi G. Sanders,
I have a 1999 Jeep Cherokee Sport which I love and has a K&N filter and approxmately 140k miles. I'm not sure if we are having the same problem but here goes; within a few minutes of cranking up, my Jeep goes through a "chug period" for a few minutes. During those minutes it seems it is not getting fuel.I cannot trust it to pull out in traffic because it seems to lose power during this time as well and sometimes backfires. After a few (maybe 3-5 minutes) it's fine. It doesn't matter whether it's 35 or 95 degrees, it does the same thing. I've had a Jeep "Expert" to look at it and put it on a computer but could not identify the issue. I cannot offer a solution unfortunately but hopefully some Jeep "Angel" can. It is very dangerous and I'm hoping someone can offer some advice. Good luck Jeep buddy.
