#4174 of 5134 Re: 1999 Jeep Grand Cherokee A/C Condenser Replacement [ceno]

The AC condenser is mounted in front of the vehicle radiator. If it is bad --replacement is the only alternative. The condenser will appear as a minature radiator. Its job is to release the heat from the cooling process system (as in radiator fin) via the small fins attached to the condenser ( page24-7---- 99 cherokee service Manual) Now if the problem is the evaporator coil( finned device thru which cold refrigerant liquid passes----and hot air in the car passes over and is cooled) is bad---then the dash job is required. The evaporator is located in a common housing with the heater coil assembly---inside and behind the dash----S Swann

First, I assume you mean evaporator. The evaporator is under the dash. I have a 97. I bought the Chrysler shop manual on ebay. In the A/C section they don't give any part info. They do show that heater/air conditoning is contained in an integrated housing. It looks like you pull that out and then hope you can extract the evaporator. Once you have that, hopefully it will have a stamped part number or barcode label. I am not sure, but I think the screws for the dash are not all the same length so you have to track where they go. Good Luck.

Thanks for tip. This post will close this thread and summarizes the project.
The following repairs made it run much, much better
1. Service ignition
2. Valve cover gasket
3. Pull throttle and clean; new idle control valve
4. New canister purge solenoid
5. Replace several vacuum hoses
6. Pull intake/exhaust manifolds; clean intake; new gasket
7. air filter
Individually, each one had small impact, but collectively they had big impact.
It still has too much vibration at idle which is probably due to cylinder 2 testing at 120psi instead of 150. Will address in fall.
Had my mechanic look over transmission. It was 2 quarts low !
Now works great. I serviced the pan and the new transmission fluid is not red anymore. It's clear and I am paranoid about overfilling.
Thanks to everybody for their help
#4177 of 5134 99 JGC noise
Jul 06, 2008 (1:37 am)
So I've spent some time searching the web and this forum to see if I could solve my problem without posting...but alas.. I seem to be the only one with this issue. I got my rotors rotated today and when parking my JGC tonight I heard a whistling noise. It almost seemed like high pressure air being leaked out right below my passenger doors. Any clues as to what this could be? Should I have it looked at? Or is it an easy fix?

My wife's car is a Ford Escape. My mechanic says that the original rotors cannot be turned. He says Ford made them from a soft metal so they wouldn't squeal. Anyway, he said they were too soft to machine and I had to buy new rotors. He's been right so many times I don't doubt him anymore.
The composition of the pads they installed and/or compatibility with your rotors may be an issue. If you do some of your own work, Autozone may carry lubricants or cleaners designed to eliminated brake squeal. It may only require removing the tires.
For convenience, one time I took my jeep to a shop near where I work. The put on a new serpentine belt that would squeal really bad sometimes. I do some of my own maintenance, but not this one. I am no fan of the dealer, but I took it to the Jeep dealer and asked "Can you put a serpentine belt on it that won't squeal?". They said yes and they did. I did not like the price, but I knew they could do it.
If you had the work done at one of these low $ brake shops that may be the problem. Some situations need high quality parts and an experienced installer, but it's hard to judge.

Has anyone replaced the spark plugs in a 2005 w/Hemi? Both maintenance schedules show to replace them at 30K miles. Did you replace with the same plugs that were original or go with something from Bosch? Also, has anyone installed a cold air intake such as K&N?

I have replaced the plugs on my JGC 5.7 at the Jeep garage w/ factory replacements shortly before a valve spring broke and the valve went into the piston It was under warranty I have had a K&N filter on my engine since it was brand new. No problems Just wondering if you have the same problem that I have with your 5.7 engine as when traveling at any speed down the road I get a surging ( 2 to 300 RPM's) no matter what speed that I'm going ? Jeep keeps telling me that it's a normal occurance but the jeep shop forman and I don't agree with that. If you could let me know I'd be very appr.
Thanks and I hope that this helps You some what

Ouch on the valve spring!! I haven't noticed any surging. I have noticed around 55mph that it does some hunting either for the right gear/lockup on torque converter and the MDS. I've had a K&N filter since it only had 5K on it. Am planning to install a K&N air intake which replaces the box on the front of the engine with a direct route from the filter to the intake manifold. Any reason to use the OEM plugs vs. some of the higher tech Bosch plugs other than price?

When you say that you had your rotors "rotated", I'm assuming you mean that you had them turned, or machined. If so, were all four turned or just the front? If just the fronts were turned, your problem could be the in the rear. Let me know what all was done and maybe we can figure it out from there.

I have a '95 jeep cherokee, Straight 6, 4.0L. I can't figure out why I'm not getting any fuel to the engine. Replaced the fuel pump and filter already. And nothing, No fuel is coming out of the fuel rail. And suggestions would be greatly appreciated.
