A/C and Heater Blower not working

ACURA LEGEND

I own a 1991 Acura Legend LS Coupewith 201,000 miles.
Recently, the A/C and Heater blower quit working. Yesterday it worked for a short period of time and the A/C blew very cold air. Today, no blower speeds would operate, on either A/C or the Heater mode.
I hooked up gauges and, and sent some freon into the system. The gauges showed 45 lbs. Pressure.
I drove the car and all seemed to work OK. Now, after the car sat for a few hours, again the blower motor will not work.

This seems to be an intermittent problem. Any suggestions?

Could be a loose connection on the control switch or at the resistor connector.

Thanks for the quick response. Can you tell me where the resistor is located?

1. Blower motor power transistor- located behind right side of dash -behind glove box.

2. Blower motor relay-its on the blower motor housing, next to AC and Heater blower motor.
