i have an 01 cavi and i got no drls and the pass side light is super dim and ive checked every thing i can think of like,the fuses and the bulbs. I cant seem to figure it out if any one knows please let me no. thanks

 

#1 - Check and make sure the parking brake is fully releasing , the DRLs won't come on when the parking brake is engaged.
#2 - Check to see if the high beams work , the DRLs use high lamps at reduced current.
#3 - if these check out it's likely the DRL module

It's not clear what you mean so I'm guessing this is the low beam lamp when you turn on the headlights.
Swap this lamp over to the driver's side and if the problem follows ... it's the lamp.

 

Don't know if this applies to '01's, but for some reason GM used cheap connectors that will rust in mid 90 models. The connectors are located in the wiring between the headlights. Just start undoing the tape , starting at the left headlight and work towords the middle. I've done a number of these. If this is you problem, just crimp in some new connectors.
