2002 Grand Cherokee blinkers not working.
I’ve recently inherited a 2002 Jeep Grand Cherokee Laredo 4.0 L that has been sitting for 2 years. I changed the fuel pump,fuel filter, flushed the transmission, change the oil and bought a new battery. It starts up and runs fine but I have no blinkers and no low beams. The flashers do work. I bought a new multi-switch but that was not the problem. I need to dig a little deeper any suggestions? Thanks in advance. |
First of all, that's a WJ, not a ZJ. The low beams could be a bad relay. The turn signals could be a bad flasher unit. The ones in that model have 3 separate logic circuits in them. 1 for left, one for right, and one for emergency flashers. It has 9 pins on it. It's mounted above the junction box under the dash on the top of it and right behind an aluminum steering column support. Easy to remove with channel-lock pliers, but a real bear to install unless you've got slim fingers. You can make it easier by dismounting the junction box and lowering it down, but I took one look at those big gang electrical plugs and thought better about disturbing all that circuitry. They both have 52 pins in them!
