I have a 94 olds 88 royal. the blower, A/C, and rear defroster will not
work. Fuses are ok, blower relay is good. The blower resistor pack is
good but i would like to know what the resistance should be. I was
getting 1.25v on the three lower blower settings and .08 on high. Today
i pulled the the HVAC controls, I found a couple problems. the blower
switch was only working on one setting and had resistance on that
setting. I took it apart, cleaned it and all was good. Still no blower.
i checked the mode switch and it seems to be working ok, i did find a
wire with cut insulation and bad connection. fixed both but still no go.
I checked voltage at the blower again and i see 1 volt at one of the
settings and 0 at the others.
I am lost and need some direction. Is the rest of the HVAC control panel
bad? How does the HVAC control interact with the blower? I did not see
any connection between the other switches or boards to the blower
control. Only a set of wires that only went to the blower switch. Thanks
