Hey guys, having some electrical issues that I can't quite peg
My blower vent is on full blast when I start the car, or the key is in the "ON" position. I replaced the battery, and just today the blower motor resistor.
The other part of it that has me confused, is the gauge "shake" when I initially turn the key to the ON positions. Gauges shake, freak out for a second, then normalize and show everything is fine. I have no lights on, that would indicate anything crazy happening. ALSO, it seems I have no power going to the OBD port either as I have a wifi dongle, and a cheap code reader that can't get any power.
I've been through the following so far to no avail, still have the same issue:
-New Blower Motor Resistor
-Checked fuses and relays
-Checked the battery cables
-Went through as many ground connections as I could find
-Autozone tried to check the alternator, but couldn't get it straight through the battery, with the motor ground, it read 12.9 volts. (Brand New Battery)
I'm not the best with electrical stuff, however, I'd like to tackle this myself if anyone has any suggestions.
thanks in advance for anyone that takes the time and has any insight.
