are my low beams supposed be come on also when my high beams are on in my 1994 gmc sierra
You use low beam headlights when you're in a town or city in any location.
Try looking at the low beam fuse it may be blown. If no other lights come on it could be the switch.
On most vehicles, the low beam headlights are the outside pair of lights. This is true when the headlights are side by side. When the two sets of lights are stacked, the low beam headlights are usually on the bottom.
Low beam headlight should illuminate 85 feet of the roadway. Newer low beam headlights illuminate more of the road than older headlights.

It sounds like the low beam/high beam switch is bad. Fuses are not the problem since they are built into the headlight switch and would cause headlights to blink or not come on for both high and low beam headlights.
Check the grounds for the headlights.
Low beam headlights must be turned on when driving in low visibility conditions, such as at night, in fog, rain, or snow, or when approaching other vehicles.
Yes, headlights must be on low beam within 500 feet of an approaching vehicle.
I was looking at the 1996 Mercury Grand Marquis Owner Guide and it shows that you can change each of the ( 4 light bulbs for the 2 low beam and the 2 high beam headlights ) ( the low beam headlights take bulb # 9006 ) ( the high beam headlights take bulb # 9005 )
The 1999 Chevrolet has a separate fuse for the low beam headlights. The low beam headlight fuse, can be found in the fuse box.
Check fuses and bulps.
