I have a 2006 Pete 379, left turn signal is working fine, but when I go to put on the right turn signal, it’s flashing on the exterior but not on the inside panel, can’t hear a clicking noise either. the signals on the exterior are flashing very faintly, and dim compared to the left hand signal. I was told by peterbilt the truck doesn’t have a flasher but a turn stalk module. Any suggestions
I'd almost bet money you've got a broken ground. Check and see if all your right blinkers illuminate. If there is one bad fix it and I bet your problem goes away
One my 01 pete anytime my blinkers act up the first thing I check is my taillights and 99.999% of the time one is burned out or broken wire
what’s happening now is that my rear panel right signal on the truck, trailer is working. But there happens to be no right signal in the headlight, and mirror light outside. So on the front end of the truck. I checked the turn stalk module (P21-1012-402) behind the dash with a tester pin and it only is giving out 7 volts
