When the high beams and heater are on at the same time in a vehicle, it generally doesn't cause any issues because they operate on separate systems. The high beams draw power from the vehicle's electrical system, while the heater uses engine coolant and a fan to provide warmth. However, if the vehicle has an older or weaker electrical system, using both simultaneously could potentially lead to dimmer lights or strain on the electrical components. It's always best to monitor the vehicle's performance and consult the owner's manual for specific recommendations.

Why would the high beams on a 1994 Thunderbird work when the low beams do not?

Headlights have two filaments; one for low beams and one for high beams. There is a good chance that the low beams are burnt out. This doesn't necessarily mean that the high beams won't work. However, it's not too common for both low beams to burn out at the same time. Of course, it could be a fluke. I would replace the headlights with new ones and then go from there.

2000 Monte Carlo headlights will not come on you can hold the turn signal switch on to have high beams light up but high beams will not remain on?

I have the same problem. My high beam switch finally stopped working and now I have to hold the switch in order to keep high beams on. Did you find a solution, or does anyone know what the part number is or how to change the high beam switch? My 2000 MC just started doing the same thing recently :(


Fog light switch on the 2002 Ford Explorer XLT?

It's the same switch as is used to turn the headlights on, just pull it out. The driving lights will not work at the same time as the high beams so make sure the high beams are turned off.


When do you use high beams?

High beams are just higher-powered/brighter headlights, so they are used when it is dark out, but only when no other vehicles are either in front of you going the same direction or coming from the other direction in the other lane. Usually high beams are used on highways where there are no street lamps, during the late hours of the night when there is little traffic. Also, if it is foggy out, high beams won't help visibility - that's what fog lights are for. Using high beams in fog will make visibility worse.


Why do the high beams work but the low beams do not on your 1998 gmc?

I'm not sure if it is the same on a 98 as an 04. But on an 04 there is a relay box under the hood that has a relay for high beams and a relay for low beams. On an 04, it is on the driver's side behind the battery. You can check the relay by popping it out and exchanging it with another one that is working. Hope this helps
