Electrical issues

Post by Bcook203 »

Hello all, so..... My lights are on, but the light indicator, fog lights, and gas unlock switches, nothing works. I am unable to use my high beams, if I pull on the information stick (?), the high beams come on, but won't say on when I let go of it.
The LED screen inside my speedometer as well as the LED screen inside the tachometer, and the LED message screen, as well as the radio display. are all very lowly lit. you can only see the display early morning, or night. I can't see it being a fuse issue, because it's lit up but dim on the dash. Thank you for any help.

The problems you've described are due to a bad light switch module (LSM). There's a circuit board in the LSM that can go bad and in my case it was a bad solder joint. I could flex the board some and get things to work and eventually reflowed the solder joint causing the problem for the fix. You can try to repair it or these LSMs are common at salvage yards and easy to remove.
