my 94 t4r
 

Recently i have been having problems with the turn signals on my truck when i hit the brakes the right turn signal lights up every time and . When i have the right turn signal on and i hit the brakeit stops blinking .it does stay lit but it does not blink until i let of the brakes . When i turn on the left signal it works normally until i hit the brakes the the signal and brake lit blinks along with it. also what is very strange is that when i turn the right signal on at highway speeds my engine surges up and down with the blinking of the signal. someone know wtf it is?
