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.
Great thanks for showing problem with turn signal relay. Left turn signal did not work right only front blinked rapidly. Could not see bad solder joint but re-soldered all of them. Fixed the problem and saved many hours of trouble shooting. Many Thanks
Yes yes yes. I am so excited. I am a newly wed diy’er and My husband tried to fix this prob and gave up. He was going to go buy a new switch but i told him we dont buy things until we are both unsuccessful at fixing it. I knew the switch wasnt the problems from other forums i had read. But none were as specific as this. It took me 30 min and the pics were a huge help. AND IT FIXED THE PROBLEM!!!! Thank you and this is a must share since we know lots of jeepers.
Work the hazard switch back and forth 10-20 times. If that does not clear it up you will have to do some testing at the multifunction switch and at the combination flasher. You will be looking for switched ground on the light blue/white wire, terminal 8 at the multifunction switch, when the left turn signal is activated.
Ref a 2002 GC Jeep; left turn signal does work at all front or back; hazard lights work, so I know the bulb is good; right turn signal works fine. Is there something obvious to check…tks, mac
There’s no response at all when I try to use either turn signal and the hazards. Just for Jeeps is selling flashers for $50, is that reasonable?
