The relay for the blower motor might be stuck , or the switch is bad . I have a 1983 Oldsmobile 88. A few days ago the blower motor for the A/C, Vent, Heater kept running after I turned off the ignition and got out of the car. It is located under the front hood in the engine compartment against the firewall. I went into the store and when I returned it was still running. Later that day the A/C stopped working. Well it wasn't the AC it was the blower. It didn't work on AC, heater, or vent. The manual I got at the autoparts store indicated a couple of relays under the hood, under the dash on the right and left sides, and fuses also. I swapped all the relays to find out if it would start working and something else would stop but the blower still would not run. The next day I went outside to find the blower was running when I walked up to the car. I started the engine and the a/c worked fine. I disconnected the blower plug under the hood to prevent the battery from going dead. So I have two problems. The blower running with the engin off, then it not working at all for two days. If anyone has had a similar problem please comment. Also where specifically is the blower relay. I don't think I have found the correct one. Thank you, Mark

For the 1989 Dodge Ram, the heater blower motor resistor can be found on the passenger's side, on the bottom of the heater box. It is beside the blower motor.

Blower motor is located on the firewall behind the engine.

Under the hood to the left of the blower motor mounted in the housing on the firewall...

Only for the high speed. The lower speeds are controlled with the use of a blower motor speed resistor.

Either the blower motor fan switch is bad or the blower motor resistor pack is defective. It is more than likely the blower motor resistor pack.
