My clutch started acting up , and I lost 3rd gear .. this is no problem i can fix that.. the problem is that since this happened , every time i use the clutch to shift , my head lights get real dim...they will stay dim till i let off the clutch... just even barley touching the clutch i mean barley..they still dim... when foot off clutch they go back to normal.. im thinking a wire touching it , or reverse switch going out..lost for the first time on a mustang..
