The heat just stopped working all of a sudden.I replaced the blower motor yesterday and the heat stil doesn't blow out. Could the problem be that the fan swich went out?

Yes, the blower fan is inop on all speeds.
No, I don't own a mulitimeter but I may be able to get one.
I took a shot and replaced the blower because I figured if the regulator was bad the switch would have worked on certain settings and not just went all the way out.

Alright get the multimeter and put the fan speed on high and see if you have power at the blower motor. Then check to see if you have 2 ohms or less to the ground wire. Check each wire seperately so we know what were missing. Also make sure the terminals are not open on the blower motor connector. Let me know what you find.
