I had my a/c on today, and all of the sudden it statred to not blow much air at all, I had it on high and it went down like it was on low. I turned it off , and then back on and it went back to full power for a minute then went to low again. I was wondering if this is the nature of the blower motor going bad? Anyone know what it could be? Thanks

its possible the EVAP core is plugged up.

if you take the blower housing off, you will see the evap core in the firewall. try cleaning it out

ok I'll try that. If it doesn't work is it likely to be the blower motor?

most likely. even if cleaning the evap doesnt work its worth it, because you'll never get full airflow if its plugged

Yes, that is a symptom of a motor going bad if it starts up fast but loses speed on max setting. On the high setting the blower motor gets battery voltage, it doesnt go through the resistor. Is is possible (also probable) that the evaporator coil has some plugging ( mine did) looking at the age of these cars but that would not explain it starting strong than getting weak. Check the voltage at the motor when you start it and later when it gets weak. If the voltage is the same than you probably need a new blower motor.
