im not sure if yall can help me but i figure this has to be somethin with the transmision or something of the sort. well my reverse lights dont work i noticed that sometimes when i get it in between park and reverse that that flicker on and no the bulbs arent burnt out i was wonderin if anyone knows how to fix this

 

Replace the switch at the base of the gear selector.

 

can i get the switch at any parts dealer? and is it fairly easy?
