    We have the same problem. We have changed out everything except the heater core. Flow seems to be OK. Could it be the valve going into the core>

Even though I let my car run for 20 minutes to warm it up, when I get in the heater is still blowing out cool air. When I start driving, it blows out warm air. But when I stop for a stop sign or light,...


check the heater hoses going from motor thru firewall to heater core / if they get warmer when motor is at 2000 rpms or higher then most likely problem is heater core stopped up / if the hoses dont change then thermostat could be stuck open ! good luck

Blower motor location 1990 geo prizm


In my 1992 it is underneath the dash on the passenger's side, but you have to take the whole front panel including the glove box off to access it. When that is done there is a rectangular housing and a more circular housing. On the bottom of the circular housing there are three screws that hold the blower motor up. Remove the screws and it will drop right out.
