Hello all, I need your expertise I installed a new Pioneer 4800 Radio on a 4-runner and after doing the installation radio works great except, I've noticed that the display on the air-conditioning was not lit. i tried adjusting the dimmer, but it still blurry. can anyone help me... thanks in advance

Also I did NOT un-plug any plugs that is connected to the air-conditioning unit.

It sounds like one of the plugs in the back is unplugged or u may have blown a fuse, i would try checking all the fuses then pull out the ac controls and check the connections.

Well, those bulbs do burn out. I have seen my share of the display gone dark and its just bulbs. Going from memory, ther eis 3 and 2 are the same, one is different. Kinda spendy and a dealer item only, but I'd bet its no more than just bulbs.

all fuses are okay.
