Last week the dash air stopped working. Have traced it to something between the control panel on the dash and the blower motor. Can anyone help me find the fan speed control resistor assembly on my 98 Windsor?

Check on the passenger side, outside firewall mounted up high.

Normally if the resistor pack fails the fan will run on high speed. If the fan is not running at all it may be a fuse and/or the fan itself may have failed.

Hello and

Have you checked the firewall? If it is not there then parts of the dash may have to be removed to gain access to the blower motor housing where the resistor pack is probably located.

Have looked at the firewall via mirrors etc. I had been looking for a standalone item, but today saw a plug with 4 wires sticking loosely into the A/C housing. It was held by 2 screws - one missing - There is something on the other side of this plug - which I guess is the resister assembly. If I can grow my arm about 4 inches over nite, I'll probably be able to remove the remaining screw tomorrow.
Today I discovered that if I used a ground wire directly to the fan - it would run, but only on high - which is probably further evidence the resister assy is part of the problem.
