Volvo heater relay93 Volvo 850 heater motor relay is on the heater box towards center of car. That is without the digital climate control. There are two relays side by side, my relay has bad points and a blue cover. The resistor pack could also be your problem, it is on/in the heater box also. The heater box is below the glove box in front of passengers knees. The Dealership refers to the resistor as a power unit (for auto climate control) systems. When this fails, the blower motor will not work. No heat or A/C. A different resistor is required for manual climate systems. To access this unit, you will need to remove the the glove box , the support bracket for S.R.S (passenger side) , and possibly the wire harness. There should be left of the blower motor, the resistor. New up to $300. salvage yard $6-25. Try Crazy rays
The a/c heater blower motor for the front unit is located at the rear right side in the engine compartment behind the air duster......... The a/c heater blower motor for the rear unit (if equipped) is located in the rear a/c housing below the armrest..........
On the auto temp unit it is called a blower power module.

1. Passenger side dash - remove the glove box 2. Passenger side (just above foot rest area ) - remove the lower dash panel if so equipped 3.

remove the heater unit and heater matrix to acess the evaporator. separate the blower motor housing from the heater.remove the 2 clips at the front of the heater. remove the small clips between the blower housing and the heater housing.remove the temperature flap link rod.remove the 16 clips that holds the uper and lower halves of the heater unit together. remove the 3 screws that secures the top half of heater unit( 1 behind each vent a 1 above the vent outlet and 1 above the pipe connection). lift the top half of the heater unit lift out the evaporator.
mounted on the a/c unit near the fan for heater under the hood
No heat can be a clogged heater core or a thermostat stuck open. No low speed blower motor is a defective Blower Motor Resistor Pack. I suggest you drain and flush the cooling system with the heater set at hot. Replace the thermostat with the correct temp unit, pour in a 50/50 mix of antifreeze and distilled water, and bleed all air from the system.
* Disconnect the negative battery cable * Remove the glove compartment and right lower dash panel * The blower unit is located in the passanger compartment above the right front footwell * Disconnect the flexible tube and wiring connector from the blower unit then remove blower duct,vacuum hose and the blower unit retaining screws.Lower the unit from the dash * If the motor is being replaced transfer the fan to the new motor

The heater blower switch and the electrical plug attached to it may be at fault. Remove the heater control unit from the dash and inspect the plastic electrical plug attached to the blower switch, you may see it has melted. The switch and plug is available from your local auto parts store.
