1988 Ford Tempo blower motor

I assume that you are talking about the blower. it is on the right side under the dash. easy to kick the wiring loose if the under dash panel is missing. remove the panel if its there and the blower motor is held in with 3 or 4 screw and a plug in. pretty simple. good luck. if the heater core is bad, better get a manual to see if you want to tackle it. it is considerably harder to change.
