Dorman - OE Solutions HVAC Blower Motor Resistor P/N:973-018
If a burnt-out resistor has left your heater and A/C fan stuck on one speed or not running at all, this Dorman blower motor resistor, part number 973-014, is a direct-fit replacement for the 1991-2003 Ford Escort and 1991-1999 Mercury Tracer. Dorman designed it to match the operation and performance of the original equipment, so it can take the place of the failed unit.
The resistor works with the blower motor to provide the fan's lower speed settings. This lets the climate control system move air through the cabin at the speed you select for heating and cooling.
A faulty switch, wiring or blower motor can cause similar symptoms, so diagnose the fault before replacing parts. See the Buyer's Guide tab for engine-level fitment details.

What does a Dorman hvac blower motor resistor do?
It works with the blower motor to provide the fan's lower speed settings, so the heating and A/C system can move air through the cabin at the speed you select.
Does this Ford Escort blower motor resistor also fit the Mercury Tracer?
Yes. It is listed for the 1991-2003 Ford Escort and the 1991-1999 Mercury Tracer. The Buyer's Guide tab has engine-level details for your vehicle.
What are signs a blower motor resistor may need replacing?
A blower fan that works on only one speed, or not at all, can point to a failed resistor. A bad switch, wiring or motor can cause similar symptoms, so diagnose before replacing.
Is it a direct replacement for the original resistor?
Yes. Dorman designed part number 973-014 to match the original part's fit, function and performance on the listed vehicles.
How is this resistor quality-checked?
Dorman states it is thoroughly examined and validated to perform safely and effectively. A team of US-based engineers and inspectors stands behind it.
