Those sound about right. I haven't measured the voltage, but I have measured the resistance of the three taps on the resistor, which are 1.0, 2.0, and 4.0 ohms. The blower motor has a coil resistance of 5.4 ohms.
High completely bypasses the resistor, so if it sometimes doesn't work on high, then it's definitely not the resistor. I would check the contacts on the blower switch and also the HTR relay. |
