Highbeam/TS switch question
 

Just recently, my ts switch began to turn on the highbeams whenever the t/s cancels. PO had h4's with no relay (first thing I did was add one-a year ago, around the time I bought the car) but switch was ok for a year. Suspect the switch is toast, but was wondering if anyone has seen this and whether it could be a cheaper fix. The wheel, if it matters, is a momo with their adaptor using the stock "cancel ring".

It has the potential to really annoy drivers in front of me, no?

Re: Highbeam/TS switch question
 

personally I'd change the ts switch and light sw and then forget about it forever.. and as long as your in there I'd replace the elec part of the ignition sw if over 100k.

Same problem, same situation, same car (I'm assuming the '85 Targa...), - bad switch. You can usually get a used one for not too much money ($25-50). It's a quick cheap fix. Replaced it and have had no problems since then.

There's other threads on the same topic, try a search.

h/l switch
 

I had problems with the h/l part of the switch. I have an h4 installed but I am told this is not really the problem.

The electrical contacts get old or dirty and then have a higher resistance which causes them to heat up. The follower that bares on and separates the contacts is plastic. This is the part that heated up and failed for me.

I really thing dirt caused the problem for me.

I removed the switch and have fixed it using epoxy to build up the melted part. Because I had ordered a new part, I installed it anyways but now have a backup.

Good luck with yours :)

yep. this is the routine destruction caused by carrying to much current for its design.
