Why is my heat or air is not blowing and car is running hot


How hot is the engine running in degrees f? Does the radiator fan run?
With hvac turned on, check voltage and ground at the blower motor. If good voltage and ground, suspect the blower motor is faulty.

Blower fan not working


The resistor bank is bad for slow speeds, the switch is bad for high speed. In your test, you have voltage, but the switch wont carry the amps, to run high speed. Open circuits will not blow fuses. Replace both switch and resistor bank for all speeds. Make sure to clean leaves and trash from fan housing and see if fan spins freely.

Volvo s70, 1998, heater not blowing hot air


Are you getting coolant flow through the heater core? These cars have common problems with heater cores but they are easy to replace. IPD has a Video on U-Tube with step by step instructions. Also if you are in very cold weather have you checked your anti-freeze? I saw a Toyota last year freeze completely because of no anti-freeze. It took days to thaw out the heater core and they were lucky that the ice did not blow it apart. It took me hours of starting it and running up to a low temp and shutting it down to get it drivable.

AC/Heater blower fan stops blowing air into the cabin when I accelerate.


Usually a vac leak. I would check for a leak in the HVAC control system and the line thru the firewall to the engine.

Heater blower not working


It sounds like your cabin air filter has stopped up common problem on these cars. You have to remove the glovebox to get to it. If this filter stops up, your fan will be running on high but hardly anything will come out of the vents.

Hot and Cold no Blow


Most likely it will be the blower. Check to see if there is power to it, and then ground it. If it runs, the blower speed control is likely bad. If not it will be the blower motor.
