My truck is showing symptoms with the warning sounds. It does not beep when the seatbelt is not connected but the seatbelt light flashes, also, the warning light for the lights being left on did not work when I got the truck and then it started working. I did not think much off it because I thought it was probably a bad connection at a switch but now I wonder.

I will probably take back what I bought and have to swap it for the real part and that I will put in.

 

My email to Haynes about the part that their book calls the wiper module but does not show where it is got a returned email still calling it a wiper module but had four pictures attached (location, testing, etc.) for a Central timing module and a Generic electronic module.

 

Post 'em! It could help someone in the future...

 

Don't forget to pull the battery cable first. I hate fireworks in the wiring.
