The only "reset" that I know of is the fuel maps. Disconnect the negative terminal of the battery for 5 minutes.

But I don't think that will fix it. Did you unplug any connectors or tap into any?

The interior “courtesy lamps” are inoperative on an applied vehicle.

Did you disconnect the battery before starting?

Also, did you disconnect or tap into any wires?

 

[1_Mean- mo]

yes disconnected battery the reconnected it to check pwr/sw pwr

from dome light. every thing ok

then disconnected batt and hooked up player ....reconected bat

and nothin??

 

[Enforcer]

Well that should be ok. How did you check pwr/sw pwr? With a DVM?

SM says fuse no.21 (10A) located in fuse block.

Will have to read further, the entire interior lighting system appears to be controlled by the BCM.

My car was delivered that way. The dealer had to order a new circuit board and replace it. Be sure and take BOTH keys with you because they have to be re-programmed when the board is replaced
