97 astrovan issues

[1stephen2]

I have a 97 astrovan 4.3l awd minivan and my front heater blower motor keeps cutting in and out at various times under various conditions. Can someone shine some light?
Thanks

Make sure that the connections to the motor are not corroded or dirty or loose. almost sounds like a loose connection or ground wire. You can hook up an OHM/VOLT meter to the motor connections and then turn the switch on to see if you are getting voltage at the motor. Wiggle the speed switch to be sure that it is not going bad. If you have current at the motor then it might be time to change it..
