1996 Grand Cherokee- I have questions! and a problem

Alright so i've got a 96 GC with 260k miles on it. It runs great and is very reliable but I want to restore it to as close to new as possible I was wondering what should I do? I would like to do as much of it on my own as possible. I am mechanically inclined and work on stealth bombers for a living so I am up for any task. First off, it was raining pretty hard today and I noticed that rain water was leaking from below my glove box I've only had my jeep for about a month now and I tried tracing the leak but didn't have such great luck. I recently had a new windshield installed because the previous one was cracked is there any way i can test the seal of the windshield? when the new one was installed the man had to remove the windshield to even access the seal. As far as I could tell he did a good job I watched him as he did it. I am thinking maybe water is running in from under the hood? Any ideas? thanks guys

try running a garden hose where you suspect it is leaking from. Start down low, and work your way up, and you should be able to find out where the water is coming in.

With that said, I think you will have better luck over in the XJ area. This is the FSJ (Full Size Jeep) section. Just a F.Y.I. They stopped making full size jeeps in 1991.

Pop off the windshield wipers and remove the plastic cowl cover. Check that all your drains in that cowl/AC intake area are free of leaves and other things that can block the drains causing it to back up and flood in through your AC/Heater intake. Also check the AC Evap drain line where it runs through the firewall on the lower passenger side, make certain its clear or all the condensation from the AC and any other water that enters the Evap/Heater box will make its way onto the floor on the pass side. I would be leery of the windshield seals though.

Ditto I missed the service part. Thanks to men and women like you I have the things I have and associated freedoms! If you were close to Austin I would be glad to help find and fix it.

There is a reason a good number of jeeps have passenger carpet cut out, common problem either A/C or cowl intake as stated above or maybe both.

+1 on cowl seals

The orange stuff in this pic is where I resealed. Your old sealant is probably white or grey and likely is dried out and cracking. Scrape it out and replace with new RTV. I didn't have to remove the cowl shield to do it though.

Welcome to the forum and thank you for your service!

Yeah, hopefully adding some RTV next to the cowl will fix your leak below the glove compartment when raining.

If you ever have a wet passenger floor when running the AC system you may want to follow the below procedure for clearing the HVAC box/housing drain line. Not the best design where you can't get to it to clear the clog and it empties into the frame. I usually use a small wire for pulling any stuff to the inside after drilling the 1/4" hole. Watch running full psi compressed air up in there and use maybe 50psi. I just put a piece of duct tape over the hole rather than a rubber plug covered with RTV and it doesn't leak.

Noticed in your 1st post you have a 96 Grand Cherokee (ZJ) so you may want to change this to 1996 ZJ in your profile. A XJ is a Cherokee. You may also want to fill out the below Chrysler/Jeep form and they will email you a build sheet in a couple days listing exactly what came on your ZJ from the factory. In the 1st box on the form just type, "Request for build sheet" then in the 2nd box you can request a list of any recall work which has been completed. They won't know what has not been completed unless done by the dealer or a shop which reports it.

Just ask if you have any questions and good luck!
