Searched~ G20 The AC/Heater fan switch does not work at all. the fan stays on hi

Now i did find somthign about a resistor but they said the fan does not work on like 1 - 3. Now my girlfriends 1991 G20 the switch does not adjust the fan speed at all

The fan just stayes on high does this relate to the resistor also?

Thanks.

I believe your problem is more the control unit it self. When I had a g20, mine did some funky things as well, like not switching from from vent to defrost, etc... You can try the resistor, its a easy job and cheap.
