Why driverside lowbeam not working has less voltage at lamp connector than other lamps 2001 buick regal gs

You have probably burnt up the element as it is a 17 year old seat now. The elements are replaceable, but the labor is pretty spendy. To test it you will need a multimeter to check for continuity across the connectors that go to the seat heating elements and check for voltage at the car side of the connector. If you have 12v to one side of the connector and continuity to ground at the other side, and do not have continuity to the seat side between the connectors, you know it is a bad element.

check sensor on reservoir. Unplug connector to sensor to see if light goes out. If yes, replace sensor. If no, wire may be shorted.

Check from your turn siganl fuse, from the cluster switch to the sequential switcher unit. Use a multimeter to check for the voltage that has to flow through these circuits. Finally trace them to the front and rear lamps. If the volatge is absent on any of these units you will need to replace. So check once again fuse, switch and Unit. You can use a 12 test lamp to also check the voltage even without any mltimeter. Hope this advice helps you to identify . Good day

star by checking for voltage at the rear sockets, if not check the ground connections

Check the connector to the light,and the ground ,if this checks out o k,then replace the left head light relay.

the casing for the lamp assembly and mirror is held down by tiny clips.. you'll need to slide the assembly to one side in gently pry at the housing to pop it off.. it shouldn't take too much force to get those off

my tail lights on a 2002 buick regal do not go on when lights are on, I changed a couple of the bulbs still nothing, brakes lights and backup lights work.... also the inside dash lights do not work could it be a related problem,

Bad ground RR tailamp ***'y,whether broken wire or corroded lamp socket. Start there as these can be tricky to trace. Look for the obvious first then seek a good electrical diagnostics tech.
