Introduction
This troubleshooting guide is intented to help identify and repair specific electrical system problems. The following is a list of problem symptoms discussed in this guide:
| Relay X Bad. | Remove Relay X from terminal board and install jumper in place of primary contacts to see if functions are restored. | N/A |
| Flaking of instrument bezel reflective coating, burned out bulbs, or bulb wattage too low. | Refer to Instrument Panel Light procedure. | ELECT-08 |
| Damaged lug, damaged grid, loss of power. | Refer to Rear Hatch Defroster Troubleshooting and Repair procedure. | ELECT-05 |
Battery goes dead after a short period of time.
| Possible ground on electrical system. | Use the Excessive Battery Discharge Rate procedure to try and isolate the problem. | ELECT-26 |
Fuse #11 Blown (1985 through 1989 944, 944S, 944S2, 944 Turbo)
| Ground in glove compartment light wiring. | The red wire located on the glove compartment light of 1985 through 1989 944 series cars could rub against the metal brace above the glove compartment causing fuse # 11 to blow. This could be an intermittent condition. | To repair this, bend the red wire down away from the brace or switch the red and brown wire positions on the light assembly. This problem was addressed by TSB-98902. |
One of my instrument panel gauges is not working properly.
| Faulty gauge, sensor, or wiring. | Troubleshoot using Sensors and Gauges procedure. | ELECT-19 |
My turn signal blinks faster on one side than the other.
| Dirty bulb socket or bulb contacts. | A rapidly blinking turn signal on one side is the result of a dirty bulb holder or dirty bulb contacts. | Remove the turn signal bulbs on the side that is blinking rapidly and clean the bulb sockets with a wire brush. Clean the contacts on the bulb with emery cloth or other mildly abrasive material. Coat the bulb contacts with a light coating of dielectric grease and reinstall. |
My turn signal light comes on but does not blink.
| Bad bulb or flasher relay. | If your turn signal light comes on but does not blink on one side, you most likely have a bad bulb on that side. Remove the bulbs and determine which bulb is bad by looking for a broken filament in the bulbs. If the turn signal lights come on but, do not blink on either side, your flasher relay is most likely bad and should be replaced. | N/A |
