Hello all, today i installed a Computsar CS-800S in a 2007 Hyundai Sonata (basic key). Did a full check on all systems prior to install than checked most of them after install. I did not wire parking lights as the owner did not want them to flash.

I received a call earlier from the owner saying the dash lights are not coming on. Tomorrow i will check it out. Just seeing if anyone can think of what to check?

Thinking it might be a unplugged dimmer switch. Or a blown fuse. Anything else someone can think of?

 

Found the problem.

Apparently the ESC and Dash dimmer switch plugs and be swapped (same connector). A simple swap of them and everything was A ok.
