A couple of electrical problems

[aidandj]

Hey guys,

Summer time finally came around and I have some time to work on my truck. I have 3 main problems.

Note: I have checked all the obvious fuses for these problems.

1. Turn Signals: The turn signals work, except when i turn them off sometimes the flasher continues to click. The lights are not blinking, but the flasher is making noise. I have replaced the flasher.

2. The interior dome/map lights do not work, and neither does the garage door opener. All the fuses are there, they just wont turn on.

3. Also this one seems easier but when the heater/AC is on then I can hear a noise coming from the fan. I can smack it and make it disappear sometimes, but cannot for the life of me figure out how to access the blower.

Any help is appreciated.

Thanks,

Aidan
