Hi i have a 92 f350 withthe 7.3 and and e4od tran. I took the truck through a car wash the other day and after that a couples hours my left blinker stoped working and jsut stayed lit. Kinda thought it was funny but hten jsut figured the flasherwas shot so i got a new flasher put it in and still did it. THen i noticed when my lights are off and i turn the left blinker on the roof light **** well as all the ouside lights flash as well also the dash lights to except headlights. And whe ni have the blinker in the off position and i put it to the left turn position wheile im cruizing the truck upshifts and when i put it back she downshifts. IF someoen can help me out on this wierd problem it would help thank you
