A/c, heater turns off an on .
I seen on here that to fix the ac heater off and on problem ,is to replace the blower resistor.. I replaced mine with a new one, an still no change . Blower seems to blow good high and low when its on. I know a lil about wiring. is there anything I could look into . Or should I replace the a/c heater controls/under the radio ? Thanks in advance.
