Clock, Radio and intermittent wipers don't work

I bet you have an aftermarket stereo head unit and that the installer tapped the wrong wires for the clock
and spliced into the lighting circuit, which uses some funky floating ground to dim the cabin lights. There are a lot
of wires for the lighting on that sub-harness and it seems to be fairly common to fuck something up with the lighting.

Whether or not this is related to the intermittant wipers, i don't know. But, i would pull the stereo/climate cluster
and unplug the blue and white sub-harness connectors located to the back and lower right and see if that affects the wiper
operation.

Thank You Z_Karma. I suspect you are right. I do have an aftermarket stereo as well as an Indiglo climate control face which has been installed for a few years.

It's possible that I have shorted out a circuit since I use the ashtray to keep my change in and open and close it daily. Thanks again.
