I have a 1997 f150 supercab and the left turn signal keeps blinking after the truck is turn off, also the dash lights will not come on when the headlights are turn on and the blower on the heater will not work. I have checked all fuses and they seem to be ok. I am stumped. I just got this truck.

 

lighting issues sounds like a faulty headlight switch. The blinkers are also ran through the same switch.

Blower issue, does it blow with AC on?

 

The blower will not come on for A/C or heat.
