Your heat problem is due to either a problem with a vacuum motor or a vacuum switch that moves the doors in the vent system. Should be $200 max to fix that. Coolant always flows thru the heater core so there's nothing wrong under the hood, unless core got plugged with debris (highly unlikely). If the paint is bad and/or interior ripped I would sell it, but $800 is too low if engine & trans OK. I think you could sell it for more on ebay unless it's all dented up. I have a 97 Jeep with 180K, the paint is starting to get crow's feet, but engine and trans are still good. Your miles is not too high. In TN where I live, decent vehicle costs $8-10K so sales tax alone is $1000!!

agree with other poster,lots of factors--mainly-what could you replace it with for that kinda money?..engine/tranz? tirz?body and paint are usually th last thing i worry about-that slick paint don't get you there!
--if your mecanic's gonna work on the a/c,then he should b able ta see whatsvwrong with heat-usually the valve that shuts off the hot water,when you turn on the a/c..if u can find it(by th heater core-external to heater box,inline heater hose valve)turn it on in winter,close it in summer shop around,and seee what other mecanics want-but your estimaste ain't bad..
cars today got LOTS of crap to go wrong,so-learn to fix it yourself,or pay th piper!?!

Jan 22, 2011 (6:16 am)
I have a 2001 Grand Cherokee Limited with a couple of heater issues. I did the test to check the computer and got no codes. It just had 00 and when i kept turning the know it just counted up to 99. (not sure if its suppose to do that or not.)
Firsr issue is the heater is intermittingly shutting off.. There is still power to the display but it will shut off the blower while im driving pretty frequently now.
Second I am getting poor air flow out of the vents.. The air is hot however just not flowing out much.. The center vents are kinda blowing out the air but the two vents by the doors is almost no air blowing out..
Im pretty sure the blend doors are good as the air not cold and when I move the dials between driver and passenger the air does change temperature also with no fault codes.
I did have the heater core replaced before the winter and the guy said the blend doors looked fine.. I dont want to have to pull the dash out again as it was a giant pain in the a**.
Does anyone have any suggestions as to what the problem would be? Better yet how to fix these problems..

I have a 2003 JGC and took it to the "Dealer" and they replaced a sensor that said was the problem...Wasn't though. Same problem, had it taken to repair shop and they told us the front control panel shorts out. Replaced it and works fine.. It costs $120, but could get one at a junk yard if you can find a JGC.
Hope it helps...

You will have to get a wiring diagram and find the control wire to the blower motor, i.e. the one that turns it on or off. Then, you will have to splice this wire so you can connect a voltmeter to it. You can do the splice with a crimp connector tool. If you are lucky, you may be able to back probe the wire so you don't have to make a splice.
It will be very helpful to create a very long clip lead to go from the meter (-) to the battery(-). You can't measure without a good ground. Then you will have to observe it to see if the control is malfunctioning or the blower is malfunctioning. The only alternative is to guess. I learned this the hard way. I once replaced rear wiper motor on my jeep and it wasn't the problem at all. It was the switch. It's not easy, but it can be done.
There may be an easier way, but this is how I would get started.
