Have replaced the 3rd door latch 3 times - running lights go off when direction signal is on - but seems everyone has the same problem and GM does nothing to remedy it.

My 4wd Sonoma has been an excelent truck. The engine has a bit of a rough idle (from new) but runs strong and gets OK gas mileage. Front brakes wear out on the early side and now I have developed a noise in the front end, maybe worn control arm bushings. The only major repair has been a fuel pump replacement at 70k.

I have a 97 gmc sonoma and it stalls out at times while driving. the mechanic can't find the reason for it happening. He thought it was the module so he changed it but it stalled out again. I suggested that it might be the fuel filter but he said that was not possible. Any suggestions?
