I just got back from wash the truck and I noticed my 4high and 4low lights flashing, I pulled over and tried to put in either and no joy, they didn't work. I was a little worried that I lost my 4X4 and don't know why thia happened.
I wash my truck same place weekly and spray the underside as best as possible and never any problem but today.
When I got home I shut the truck off and then restarted, Lights out 4 high and low work great!
Now I did the (Pierce's) fog light on mod this week and the defroster off mod.
Any idea's out there? It’s got lots of warranty left so I can take it to the dealer (that’s what the owners manual say to do if flashing), but that’s a pain for me.
This has been happening again lately, Its very slushy out and I think water is shorting something out. Any ideas of what could be getting wet.
