Got an 01 ram 1500 with 5.9 liter. So first my ASD relay went buggy on me and the day before I figured out that was causing erratic start ups I lost power to my signals hazards and break lights. I replaced the 10 amp red turn signal fuse in the junction box and the number 5 blue cubed 20 volt fuse under the hood. Now I'm told either the combo flasher, multi switch or some other switch under the break pedal. Help me guys.

 

They all go thru the multi-function switch.... Does your high-mount stop lamp work? if it does, that would indicate the MF switch......

 

As stated above, all these lights run through the MF switch. However mechanically the hazards switch is separate from the turn signal switching so if both don't work I'd start checking the wiring to/from the MF switch first.

 

So guys I replaced the combo flasher and multi switch with no results then at the advice of my coworkers I checked the ground wires. Lo and behold behind my knee guard on the frame was a short ground wire not connected to anything and I'm the wire harness was a wire connector at the perfect distance. My silly self connected them and saw sparks. After disconnecting my dash lights and ignition failed. Thinking I fried the ignition switch I noticed lights behind the harness blinking and discovered a black box which I now know is a gps tracker. Mind you I bought this truck at an auction 3 years ago. I believe now that i have inadvertently set it off to kill the ignition. So do I remove it as is or do I have to have it reset before removing? Ahhh!@$&!
