This is an ugly job, and has many easy to break and hard to get parts inside the heater box. Let a qualified shop do this job.

How to change a heater blower on 1997 gmc safari mini van. I have I have never changed a heater blower on a gmc mini van were do i start?


If your talking about the blower motor, its under the hood. If you buy a delco part there will be instructions in the box. There is a plastic/rubber cover over the motor that needs to be cut with a very sharp knife. Anyway buy the delco part and you'll be able to figure it out from there. Good luck.

How do I get access to the heating system on a 2005 gmc safari van. The fan is not blowing on all speeds and I think I need to change the switch.


Like most GMC Vans, remove the dashboard, then the heat core cover....

Installation is the reverse of the removal procedure.

Heat


The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.

if the car is not overheating, the thermostat is working fine.... replace or flush the heater core multiple times to try and eliminate sediment build-up.
