How to replace a Left turn signal on a 1991 Volvo 740

Hello. here is how you replace the front turn signal assembly on a 90-92' 740. First, twist the the black plastic collar loose to disconnect the wiring harness from the assembly. Second there should be 2 10mm bolts holding the assembly in place. just take the nuts off the bolts, then carefully pull the assembly out. Reverse the directions to install. should take about 5mins, unless the nuts are totally rusted. if so use some BP Blaster. Good luck :)

1991 740 Wagon electrical problems

Was the car primarily in a Southern state--no winters? If yes, it could be the wiring harness that leads to the rear wiper/stop light inside the rear tail gate. They usually break at the flex point, and short to the frame.

On the 92, the belt closest to the engine goes around the power steering pump, water pump, and crankshaft pulley.

The second belt goes around the alternator and the crankshaft pulley.

The third belt goes around the a/c and crankshaft pulley.
