Electrical problems with blinkers.. anyone?
Well, the hazard lights work for a while.. and then slow down and stop. When the headlights are on, you flip the turn signal switch down and the left brake light and front marker light turn off. Same on the other side. All bulbs are ok, and the turn signal switch does not return after you straighten out (i'm not even sure if they are supposed to in this truck). anyone help with this problem? I dont want to dish out $90 for the blinker switch if that may not be the problem.
Thanks
John

Sounds like a lack of a GOOD ground return. Check the grounding of all four lamps. 95% of the stop and turn signals is grounding problems. Just went thru the problem on a '78 F-150. It can also be the contact points on the lamp(s) are mashed down. The return to normal postion is a problem in the steering wheel hub.

I had some similar problems and I straightened them out by soldering new connectors on all my ground wires and using new screws to hold them down. Although it sounds like if your blinkers are gradually slowing down, you might need to buy some new blinker-relays.
Also as ORW said, your turn-signal switch isn't returning most likely because the switch's return cam is either worn or broken. You can buy a new return cam for $15 to fix the problem without having to buy and install a whole new switch. You need a steering wheel puller to get the wheel off the steering shaft to get to the switch though (they're not expensive either).

I have fix similar problems on multiple trucks. As was said above, it is probably a ground issue. Most likely, the problem is with one or both of your taillights. Remove them from the bed and inspect the wiring at each taillight fixture. On 2 of my trucks, the ground wire was corroded away to nothing in the bulb holder. I drilled a hole through the side of the fixture and passed a wire through the hole. Then, I soldered the wire to the ground connector in the holder. I attached the ground wire to good steel and sealed everything with silicone. I never had another problem once the ground was fixed.
