Hey guys 1st time poster and didn't see this posted anywhere on any of the threads or generic faq pages.

I've got a short that's throwing my passenger driver door lock , washer fluid dash light , and other random things periodically. Didn't know if this was a common problem or if any had some help or info regarding something along these lines they ran into. This forum is great and with all the info I can see I'll prob be spending some cash on this new used truck I just bought.
135k on it and because of yall switching to Mobil 1 synthetic 5w30 instead of conv 5/20 in the coming days. Thanks everyone!
