check heater motor
The blower resistor is located behind the dashboard. It is found behind the heater near the center of the vehicle.
a 1992 Volvo 940 doesn't have a speedometer cable. the speedometer is controlled electronically.
Most likely and bad blower motor resistor.
You can gain access to the "blower motor" from the passenger side firewall under the hood. The fan unit itself should be mounted to that motor.
it's on the outside on the passenger side.near the heater core hoses.
The horn for the 1992 Volvo 940 is located under the car on the driverside towards the front bumper. Over in the corner, I hope this helps
