Why are the high beam lights on my Silverado not working?
For a few weeks I am borrowing a Chevy Silverado truck whose high beam lights are not working and I’d like to take a try at fixing it. In old cars you could just follow wires and know where the problem was but I have no…
How does a high beam light bulb work?
Get familiar with the fuses and relays that control your headlights. The headlight switch usually doesn’t control the headlight bulbs directly, but through one or more relays. The headlight switch powers a relay, which powers the headlight bulb. This protects the headlight switch from the high current used by the high beam headlights.
Why are my low beams not working on my 88 260E?
Suggest junk yard new they are about 200. The headlights on my 88 260E would turn OFF when I switched from high beams to low beams. Very unsettling the first time it happened. If I fiddled with the beam change lever the lows would come on so I knew the problem was the steering column switch. I bought a new one and all ws well again.
Why are my high beam headlights not working?
In the case of high-intensity discharge (HID) headlights, or Xenon headlights, there’s an additional component. To get the xenon and salts to plasma state, the HID generator bumps the voltage up to 30,000 V, then stabilizes around 90 V when the bulb is in operation. If the generator fails, the bulb won’t light.
Where is the low beam relay on a GM Truck?
The low beam relay is on the bulb side of the BCM, and so is the high beam, as it appears the high beam relay is operated by a relay on the BCM (which may not be a removable relay). Don’t see why it is also labeled PCM. Click to expand… soon as I get one, i’ll get on it. I’ll post later what I find. Thanks for your assistance!
