I just purchased a 2001 Grand Cherokee Laredo. The turn signals are not working. I replaced the Turn signal relay and now the left turn signal comes on solid, but does not flash. I am thinking that maybe the turn signal switch may be bad.

How difficult is that to replace. I found one at Advance Auto for around $42.

Thanks

 

Two other things to check are the combo-flasher and the tailight grounds. A lot of times the plastic in the tailight sockets melt and you lose the grounds. Do the hazard flashers work?

 

The Flashers don't work anymore. They did initially. Then all of a sudden the flashers would not stop flashing until I pulled the fuse. When the motor was running the flashers were off. As soon as I turned the motor off the flashers turned on. Once I replaced the turn signal relay that particular flasher problem went away. Weird.
