Where to start looking? my ciggarette lighter and power lumbar support stopped working. fuses are fine. what could it be?

 

for the lumbar- can you here the motor working or no?
for the lighter- is the lighter itself white.

 

Both are heavy pulls although short durations. Check fusable links for a bad one. If so, its connector might not be clean or solid. If not, check for power at the fuse. Should be hot w/o key off but check w/ key on too.

 

No its not the lighter itself, i tried a new one. And no i cant hear the motor working for the lumbar.

I have power at the fuse.

 

Do you have power at the device? If not trace the lines back to where you do have power, find the discontinuity and fix it.
