I had a headlight that had condensation and my drivers side blinker went out. I fixed the condensation problem and tried to replace the blinker but when I hook up the bulb I have problems with other things, like stereo, hazards, etc. I am now having multiply problems since a fuel pump was changed. The alarm will arm but the door will not lock or unlock. The dome light, stereo, and clock only work when they want to. What could be the problem. It seems like multiple problems.

 

maybe fuses?
