Conversation Between NBC-Steve and Snipershide22

Thanks, First find out what doesn't work. Next remove that circuit from the fuse block and start troubleshooting it from there. It sounds like you have something miss wired so I would carefully look at the factory wiring diagram and identify every wire. I suspect you may have wired in the HVAC into the fuse block. As far as the flashers I simply used the Painless flashers and removed the factory flashers. If you look at the wiring diagram it's pretty easy.

Good luck!

Hi, great truck. I joined site to ask you about the painless wiring fuse box you installed. I have a 79 f150 and started installing painless system identical to yours. I can see in your pics that I have the right side of fuse panel wired just like yours but have run into a wall on left side. problem one Fuse for Wipers blows immediately- but wipers still work. Problem 2 only thing not working is the turn signals and hazards. How did you by pass flasher relays that came on the truck? Thank you
