I have posted this in the newby area and now here. I am havin a problem with the rear blinker on my truck. Shes a good girl dont get me wrong. This just started today. The turn signal inside the truck started goin really fast so I checked all the blinkers on that side of the truck and the rear light was out. I imediately went to autozone for a new bulb. I got home changed the bulb and checked the old one. Its not burned out and with the new one its not blinking or anything and the turnsignal inside the truck is still goin fast. I want to check the fuses to see if that might be the problem. I have lost the manual to the black hole that is in my house here and need to see if anyone can tell me which fuse goes to the rear blinker. Thanks in advance.

 

The fuse box itself may have a diagram on it.

Also, check the ground for the blinker.

 

Hmmm....... Yet you didn't mention what year and model the truck is ?
