I noticed today that the blower motor on my '02 when switched to the #4 position was running at the same speed as it was on the #3 setting. Anyone have any idea what might be the problem? I know just few days ago it was running faster on the #4 position as it should.

With my 2nd gen Escorts, the various speeds result from going through the series resistor pack mounted under the dash behind the glove box. The resistor pack is in the air stream coming out of the blower to get some cooling, but even so the contacts can melt on the resistor array or the contacts on the mating connector can melt. I think the resistor pack is on the grounded side of the blower motor, and the blower motor gets its 12 volts coming to it (from the fuse block that is above the array of fuses in the fuse box that is down by the driver's left foot). To see the fuse for the blower circuit you have to scrunch down below the bottom level of the dashboard.

Hopefully the problem is not with the guts of the blower speed control switch. Getting to that knob and the switch behind it involves taking the HVAC control panel out, and carefully pulling out a part of a wiring harness that has really short wires.

By the way; does anyone now of a part number or a source for the HVAC blower control switch?

I've had the plug going to the resistor on my '94 melt a couple times in the past but instead of the fan running at a previous speed it wouldn't run at all on the effected speeds. Thanks for the reply.

I don't know what the problem is/was but I just took the '02 on about a 25 mile drive and at least temporarily it has fixed itself. I guess time will tell whether the problem comes back or not.
