Replaced my turn signal switch now my gas and temp gauge peg!

If the 2 gauges are showing full, then either:
1) the wires from them to the sensors are both shorted to ground
2) the voltage limiter behind the dash cluster is shorted out so that 12v is constantly being applied the gauge circuits

Not sure how either would be obviously related to the turn signal or pulling the column or steering wheel. Check around the violet and dark blue wires on pins 2 and 3 of the cluster connector; the dark blue goes to the fuel sender and the violet to the temp sensor.

Also, disconnect the violet wire from the temp sender on the engine, and put a voltmeter on it. Turn on the key to RUN and measure the voltage; it should be pulsing in voltage. If it is a steady 12v, then the voltage limiter is shorted. Do this as fast as you can so you don't burn up the fuel gauge, or just disconnect the fuel sender wire while doing this to be safe.
