I have a weird electrical gremlin that just started within the past few days, but I just noticed it last night.

Symptoms: When I turn the headlights on (and they pop-up, doesn't happen on the first click for parking lights) I get a single wipe of the windsheild washers. I assume I knocked something loose in a recent job but I have no idea what.

What I have done to the car recently:

-Rear wiper delete. I thought I did this cleanly by heat shrinking each connector so they wouldn't ground on anything. I wanted to pull the fuse for the rear wiper but I couldn't find it in the fusebox? This would be my guess.

-Evap Delete. I had to move the big harnesses out of the way at the rear of the engine, possibly cracked a cable and made a short?

-Bypass Valve. Possibly bumped a wire near the head lights?

-Walbro Fuel Pump. Not suspecting this really, I noticed this problem once prior to installing this yesterday.

Other ideas: Bad relay?

The PO had an alarm installed that I removed, the power lines were spliced into some wires going to the fusebox with those god damn vampire taps. I removed them and taped over where they were (I would have cut and resoldered and heat-shrunk them but that seemed impossible without taking the fuse panel all the way apart, and I wasn't getting into that mess.)

Really at a loss on this one guys. Any help is appreciated.

 

Maybe try pulling the fuse for the lights then switching the lights **** on to see if the wipers are in loom with the lights or not.

 

The first thing will be removing fuses and playing with the wipers and the headlights to see if anything seems weird.
