I have searched and think I have the answer but will give up the facts here and see what people think.. My AC/Heat blower motor will only work in high speed for AC (no med (2) or low),,, High and med/high for heat (no med/low or low). With the blower motor resistor unplugged I get only high for both..
I replaced the resistor but no change.
If the blower motor relay was bad the fan would not work at all right..?
So I am thinking I have a bad switch.. When in high speed heat I can wiggle the **** and make it switch between med/high and high speed or even cut off..
Just want your opinion on what else it maybe or just confirm that it is a bad switch from people that may of had the same problem...? thanks for the help guys
