Default So fan speeds 1 and 2 dont work....but...

I replaced the fan resistor, and still nothing. 3 and 4 work fine, just no 1 and 2 .
Ideas?

Maybe you think they are not working, but they really are? My fan is very quiet.

Default got my temp cluster used for $10 off ebay...

my setup was klinda crazy, if I pulled the switch out and plgged it in, it worked fine, but installed it didn't work. it also 'looked' perfect. I finally said f-it and installed the older used ebay one....everything works 100% now.

Blower motor resistor. apeeds 3/4 go throught the resistor in the blower itself.... 1/2 has a resistor behind the glove boxe in the 90. Just replaced mine in my 1995.

Default The switch was my problem

After I changed the resitors. Got all from the salvage yard for $30. Used switch is kinda bunk though. A year later, speed 3 is intermittant. I think I'll go over the original one and see what was wrong. Its only a cam switch and copper contacts. Allow some time to change the switch, those cables are tough to get off and back on.
This was on a 1988 90.
