I have checked the fuse under the hood and it is good can any one tell me if or where the relay that runs the 4-ways would be located. blinkers and tailights all work.

thanks in advance

 

# 4 fuse in engine compartment PDC
# 10 fuse in junction block left side of dash.
Combinatin flasher under same cover bottom left side dash.
This flasher has footprint of regular relay but is not. Do not sub.
From wiring diagram appears a bad combination flasher could cause problem.
The multi-function switch on steering column is also a possibility.(hazard switch part of it) I suspose the wire from flasher to switch could be open but not as likely.

 

dozer thanks for your reply I will check those things today.

 

I had the same thing happen on my 01 3500 It was the big sqaure flasher on the driverside end of the dash. They are like $25 or so at the dealer. I also had my high beams quit working and that was the multi function switch. Your turn signal 4 ways and wipers are all on one switch. The multi function switch is the same as jeep grand cherokee's if you go to the junkyard

 

Probably just the flasher on the inside fuse box. One flasher is for turn signals and one flasher is for 4-ways. You can get'em at NAPA. Replace it with the heavy duty flasher.
