I have a chevy Silverado with a tow hitch package. I'm try ing to wire in a new hitch because the last one got smashed, I can isolate the right and left blinkers and the brake lights, but on a 4 slot flat hitch wiring harness there is only enough slots for the right and left blinkers and the running lights. Where does the brake light go? I've tried tieing it in with the blinkers, but then every time you try to use left or right blinker the both start flashing as if you turned on your emergency lights. any help would be appreciated.

With the vehicle In Park and the ignition on, swith the R/S signal on. Now , gwt out of the car and walk to back of car and inspect the R?R signal light . OK ? Now, do the same to the R?F signal light. One of them are not going to working correctly. Replace the defective bulb, or socket

I had the same problem twice before. Solved it the same way both times. In my case it was the Hazard switch at the top of the steering column. It was stuck. I knew it was that because the signal lights had been functioning perfectly until I parked my car alongside the road with the hazard lights on to do some nighttime fishing and sip a little white lightnin'. (just kiddin' about the white lightnin')

When I got back in my car to go, I turned off the hazard lights but I had no turn signal lights! So I kept pushing that hazard button up and down for about 30 times with my left turn signal arm down until it started working again. So after having this happen to me twice, I learned a valuable lesson: Don't ever use hazard signals in this car.

I have a 1994 F150 and the blinkers and E Flashers were out. I bought some flashers from NAPA and put them in with no effect. I noticed my E Flashers were still on from before when I was trying to switch them on. Turned the E flasher switch to the off positiion and the trun signals with the new Flasher are working. I thought I had another flasher spot around the back of the fuse box but didn't have time to look at it yet, so my E Flashers are still not working.

My turn signals won't work with the E flasher on. ??? Hopefully just that, the Flasher around the back.
