I have the same problem with my XJ and applying sealant around that white box didn’t change anything, it was a lot of work. I noticed since it was raining last night that panel which you drilled a hole has a channel forming with the fender and the water goes into the engine bay and right in where the fan is mounted on the firewall. So I drilled a hole just outside the base of the fan motor on the engine side and I plan to jam rubber in that channel along the fender. Interesting thing is the channel is just a little bit wider on the passenger side than the driver’s side, water drains in the engine bay from both sides just having the fan mounted on one side means water drips in.
I have a couple of XJ's. Another common place for this leakage is the gasket around the blower motor, might want to mut water in this area and sew if leaks. I've fixed by putting self leveling sealant for RVs in this area
I have the same problem. I realized it only happened when I parked the Jeep on an incline. I need to fix the issue eventually, but until then I park on a decline or flat. That has worked for a couple of years now so I am not in a hurry lol
You know I had the same problem with my 1965 mustang. You would think that automakers would be able to make this work better... Nice solution. I do have a question about the silicone though.
I will check to see if the silicone has an corrosive effect on the metal. It was brought to my attention from the lake and the window. If so, then I will make a removal video...which will be a viral video I'm sure!.I believe I can take the fender off and access some of the area. Stay tuned...
Ok, the roofing material is approved to use on both metal steel and aluminium roofs so it is non corrosive...and it Worked!!!!! I flooded the thing and no water leak!
I had a 98 Cherokee Which leaked from the ac unit. It was caused by the drain tube getting clogged from dirt and such. The drain tube down Into the frame. So I he'd to drill a hole and clean the tube out and all the water just drained out from the ac box under the dashboard. It is a poor design of this tube. Had to plug the hole and every couple months I had to open it back up and repeat this. But the leaking stopped.
Unfortunately the XJ had quite a few quirks but the bones of them are solid...unless you live in the rust belt :) i appreciate your sub and thanks again for watching
@@MajorWeakness In reality, does that really matter. Wondering how much of a impact does that really make? It the water has a way to escape between the fender/firewall metal, it can get air from those areas, correct?
Major Weakness was getting ready to do this project but was curious when the liquid silicone fills up around the box, the water that drains into it after it rains is still able to drain and not get backed up since the box is covered around the base with the liquid silicone ?
@@MajorWeakness even with this done the drain didn’t get covered up by the liquid silicone? That’s my main concern is that after the liquid silicone is in that it can still drain out of the cowl area afterwards.
I don't have the time and place to remove the dashboard so I paid a mechanic, $850, problem solved in one day. My Jeep is 100% original. I don't agree to do this kind of jobs, unless you are using it as a mud toy, is a third world country repair engineering.
Since this video the entire dash was removed, the hvac box rebuilt and entire OEM gasket seals used to reassemble. You are correct, but most people with a 500.00 jeep cannot afford this repair.
@@MajorWeakness A few days ago, I just sold my 2001 XJ with 168K miles for $12K cash, in just one week. There are not even Jeep wheels for $500 dollars.
