So everything has been rolling along good in IDI land for me and then the other day my ac only worked on the high setting for the fan. I replaced the resistor for the fan and I had all of the speeds again but it wasn't hot out at night and I didn't notice my fan speeds seemed slow.
Next day I tried putting the old resistor back to see if it was just a junky parts store resistor but the highest speed on it wasn't fast enough either. I still have 4 speeds but they're all tired sounding. The high speed is only as fast as speed two on another of my trucks that is the same year etc.
Does this sound more like a bad fan, bad ground, bad wiring, or possibly two bad resistors? Not sure what to try first.
