I might be able to help with this. so when i had a 97 EX i had a sony xplod head unit installed and after they installed it the power locks didnt work and neither did the dome light. i looked into it and there were TWO different harnesses for atermarket CD players. on for cars with the security(cars with the keyless entry) and the ones without (DX model). dont know if this is your problem but i hope it helps!okay.. you have an aftermarket radio... and your car is 96-98.... so how do you get your interior dome light to come on when you open the door?? if it does that... on mine when the aftermarket cd player went in the light stopped coming on when the door opened
Try looking for a blown fuse under your steering wheel in the fuse panel. There are two bulbs in the climate control so the chance that both of them burnt out at the same time is pretty slim imo.my climate control lights stopped working a year ago. do i need to replace the lights or what do you thin it could be?
