#3616 of 5143 1993 Jeep Grand Cherokee - Looking for Advice
Feb 17, 2007 (5:36 am)
I really don't know how to explain the issues I have been having, I have been to a mechanic had them look over it and got it back and its still doing this. So I am looking for some help to maybe better describe the issue to a mechanic or something.
I have a 1993 Jeep Grand Cherokee, it has the V8 5.something Liter engine. I had gotten it used a year and 2 months ago, and this is the first time I have really had any troubles with it. Before I had gotten I do know the previous owners had a new transmission place in the vehicle.
The problems I am having now seem especially to happen when it gets really cold. I just don't know if its the weather that could be the cause of the issues (and there is something I could do sans a mechanic) or what. What happens is when I start it up, the jeep will run fine for a few seconds then pause like its going to stall out but keep running, so its like its this brief pause/break in the running, this happens a couple of times, and even sometimes happens (though very rarely) when I am driving. Also when I start it up my oil gauge shoots up to nearly the 80 mark, and tends to sit between 60 and 80 for a while. Also (and I usually let the jeep sit and warm up for a couple of minutes, at least 5 always). When I put it in reverse, the jeeps starts loosing power and often times enough to where it looks like it may turn off, also know and then when I put it in reverse it sounds like somehting is rattling inside just about. Though once I put it in drive the power seems to shoot back up and I can go for a bit, but once I slow down for the first curve , it starts loosing power again acting like its just going to loose enough power to shut off, but once I hit the gas it powers right back up.
Then sometimes when I am driving, the jeep will jerk really hard almost like something kicked the jeep, and there would be like a thud sound. It would do this sometimes when I had stopped at like a stoplight or stopsign.
I had just recently dropped it off at a mechanic's to have it looked at and I told them all that, at first they said it wasn't doing any of this for them when they started it up and stuff, and I told them to keep it overnight and they did , the next morning got a call saying it was done. I wasn't charged for what they did, and at first it seemed what they did do fixed it, but then this morning it seemed the problems were back with a vengence.
I forgot to add, also no check engine lights come or anything, no warning lights up.

I recently discovered that when I accelerate that dash vents act like I switched from dash to dash and floor. Then in a few seconds it returns to normal. I'm sure it's vacuum issue but not sure where to start. Did Chrisstromberg ever get his issue fixed.

You most likely have the dreaded blend door failure. It's extremely expensive to repair, unfortunately. Usually above $1000. Check this site for more information: http://www.wjjeeps.com/tsb_list.htm#HEATING
To be sure:
AZC self-diagnostic mode:
1. To enter the self-diagnostic mode, depress the a/c and recirc buttons at the same time and hold. Rotate the left temperature control knob clockwise (CW) one detent.
2. If you continue to keep the a/c and recirc buttons depressed, the AZC control module will perform a Segment Test of the Vacuum Fluorescent (VF) display. In the Segment Test you should see all of the display segments illuminate as long as both buttons are held. If a display segment fails to illuminate, the vacuum fluorescent display is faulty and the a/c heater control must be replaced.
3. After viewing the Segment Test, release the A/C and Recirc buttons and the display will clear momentarily. If there are no fault codes, the “00” display value will remain in the VF window. Should there be any codes, each will be displayed for one second in ascending numerical sequence (note: no effort is made to display faults in the order they occurred). The left side set temperature display will be blanked and the right side set temperature display will indicate current and historical codes (8 historical max) presently active.
Once all codes have been displayed, the system will repeat the fault code numbers. This will continue until the left side set temperature control is moved at least one detent position in either direction, by pressing both the A/C and Recirc buttons at the same time, or the ignition is turned off. Record all of the fault codes, then see the Current and Historical Fault Code charts below for the descriptions.
Then check your codes against this list:

Stop wasting money having the rotors cut. Replace your rotors AND your calipers next time with aftermarket parts. Rotors warp due to bad calipers.

What does it say below your transfer case shifter - quadra-trac? Quadra-drive? No info = can't help.

This is so rare it's hard to believe. Can you prove, without question, that on slippery surfaces, under hard acceleration (rear wheels spinning fast on snow, etc), that your front wheels don't spin at all?
If they turn but take extra pedal, have the transfer case fluid changed at the stealership.

Clean the throttle body or replace the idle-air control valve.

Something aftermarket with a lifetime warranty. Don't pay too much. Stay away from the marketing BS pads, just get regular brake pads. There's no magic.

If it's driver side only, it's cheaper. Doesn't require removing the dash. Passenger side is big $$$.

Check your codes by using the site http://www.wjjeeps.com. Look into the heating section on how to check the computer for fault codes.
