Fixing the dash warning lights on a Peterbilt 379
When you see a Peterbilt 379 with warning lights on the dashboard, it may be something as simple as a loose connection or a bad light. Fixing them is usually pretty easy, and can save you some time and hassle down the road. Here’s how to fix most of the common dash warning lights on a 379:
- Check the ground connection between the warning light switch and the vehicle body. This is usually done by removing the screw that holds the switch in place and tapping on either end of the wire to make sure they’re good connections. If there’s still an issue, replace the wiring harness near the switch.
- Make sure all of the connector pins on each warning light are properly seated in their sockets. Sometimes this can be done by gently pushing down on each pin until it clicks into place.
- If there’s an intermittent problem with one or more warning lights, check for a bad electrical connection between that light and its corresponding socket on the vehicle body. This can be done by using an ohmmeter to measure resistance between each pin and its socket (or vice versa). Replace any faulty connections with new ones before restarting your truck.
