2004 Grand Cherokee brake light fuse keeps blowing
First thing I noticed is that right side signal wasn't working, and after a few days my wife was telling me that her brake lights acts funny. What happened is when I turned on lights it would turn brake lights as well, but the funny thing is that the right side and middle brake light would be on and not the left one. Pressing the brake nothing happened and the brake lights were on all the times(whenever I turn the lights on they would light up together). Tried manually pressing the brake back and forth and played with brake light switch (above the brake pedal) and nothing happened. Checked the fuse and it was broken, so replaced it and started working just fine for about 20 sec. and blow fuse, after that it would blow fuse instantly as soon as I would touch the brake.
I start with replacing brake light switch and checking all the wires and harness around tail lights including the middle light didn't found any wire that seems to be burned.. Did not go to far unwrapping electrical tape but they seem to be OK. So it's not a brake light switch, and the wires and harness around the tail lights seem to be OK. Than I took off all of the sockets with light bulbs from the tail lights and was putting one by one until found out that on the passenger side top one when I reinserted socket was blown a fuse as soon as I pressed the brake. So replaced that one and it still blowing fuse as soon as I press the brake, tried to replace the bulbs and still the same.
Could it be that tail light is bad?
Considering to buy one found it on e-bay for like $35 so I'm thinking to do that and see what happens.
Anyone had a similar problem? Any help will be much appreciated, thanks in advance.
Not sure if I understand you, but I got several problemas with my tail lights because they kept blowing off after a short time, I kept replacing them. Finally took my 2004 WJ to the electrical expert. He told me the reason for it was the crappy bulbs I was using, I bought from autozone (Damn crappy chinesse parts). So He gave a new ones and car is working fine. Not sure if you have the same problem as mine.
Don't think it's light bulb even though I see your point
Sorry about that I updated a bit info I was in the rush, hope I made it more clear even though it's complicated lol, huh...
I tried different bulbs and still not working but I agree with you about those bulbs because I did replaced several in the last year or two.
Check the end connectors that plugs into the lights
I forgot to mentioned to you, check for the the plugs connectors that pluged into the tail lights. They get worn or opened up creating a miscontact, this will create a short circuit burnig the fuses or blow your lights).
