This 2000 Jeep Grand Cherokee came in with the complaint that the turns signals would work sometimes. When it arrived at the shop they were not working at all. Experience tells me that it is probably a faulty flasher assembly but a few panels have to be removed to access the flasher relay.
The panel at the lower edge of the instrument cluster unsnaps and pulls away. It has to be maneuvered around the tilt lever.
The fuse box cover at the lower left of the dash has to be removed. It unsnaps and pulls down.
There is a 10 mm headed screw in each of the lower corners of the knee bolster.
A phillip’s head screw at the end of the dash.
Two phillip’s headed screws at the top edge. One on either side of the steering column.
In the picture below, I am pointing out that there are relays above the fuse area.
The hazard/turn signal flasher relay. With either the hazards or turns signals switched on it usually only takes a slight push to make the flasher start working again. After I was sure of the problem, I used a pair of pliers to gently grab the relay and wiggle it from its socket.
I then used a couple of small screw drivers to release the side latches that hold the cover on the relay assembly.
With the latches released I separated the two pieces.
If you look closely at the upper left solder joint you should see the crack in the solder joint.
A little touch up with a soldering gun and some electronics grade solder and this one was fixed.
Sometimes more that one solder joint will have to be repaired so look closely.
A faulty bulb would only affect the turns signals on that side of the vehicle. The symptom would be that the lights that are working would flash faster than normal.
Double check and I’m sure it’s the right piece. Maybe it’s been replaced before. If it was a faulty bulb or socket would that only affect that single light or all of them? Thanks!
I do not remember seeing any of these that have glued on covers. Make sure you are looking at the correct part first. If you are, then I would recommend confirming it is the problem and then installing a new flasher.
I bought my car used so I’m not sure what repairs have been done. Following your instructions I’m to the point where I’m trying to separate the cap off the relay and it’s been glued down! Are some manufactured this way? Is it pointless to try removing the cap? A little bit has started to chip away so I’m hesitant to keep messing with it.
Sounds like you have multiple problems. It would be best to pick a single issue and correct that first. Either the most important or the easiest to diagnose, the choice is yours.
