theres a couple of things happening,and ive got a good list of symptoms, but i cant find any answers. when i replaced my sony radio with a different radio a few things started to happen, not all at once tho...
1. both dome lights no longer work or turn on via the switch.
2. the constant wire on my radio doesnt seem to work ( as in when the car is turned off, the radio completely resets. related is that...
3. when i turn off the car then restart it, i have to hit my ac buttons to turn it on, again, like it resets itself
4. when i turn on the dash lights at night, the lights on the ac dont all work all the time, ant lately, its been burning out the 7.5 fuse. mabey it needs to be replaced
5. windshield washer motor stopped working

ive done the fix to get the dome light working, but since the switch, it no longer does anything.
all the mini fuses are ok.
if anyone can help or point me in the right direction, id appreciate it.
