91 vert highbeams don't work
hello, i have a 91 vert that is having issues. the highbeams will not come on. the ftp works fine but does not flash highbeams, i jumped the highbeam relay and the highs work so the bulbs are fine. i took the highbeam/turn signal switch apart and it works fine and the relay seems to work ok, but not 100percent sure on the relay so i am assuming it is the latch circut in the insterment cluster, i tried a different one from a 90 gtu but no difference, the highs flicker on then off when i pull back on the switch. is there a way to repair the latch circut or do i need to find a rebuilt or new one? yes i did a search and found the same problem but no anwsers. thanks

I replaced the headlight control switch assy & the associated wire harness.
Got REAL lucky on the control assy: $45 on eBay. The harness I took in the butt @ dealer.
90 vert w/ airbag.
This **** is known to fry out...

ahh, you mean the cpu next to the interior fusebox icemark? the highbeam switch seems fine, i took it apart and cleaned it and it is making contact so im pretty sure it is working. I thought it was that it would not stay latched if the headlight control was damaged. are the cpu's interchangable among s5's b/c i have a 90 gtu parts car i could get one from or do i need a vert specific one?
