Craig, This has been hashed over 3 to 4 years ago and nothing beats replacing the CB with the max of 5 amps over. Then if you have a marginal condition of the blower motor you might think about replacing because age of the units draw more current. Then go to Wal-mart and get a small clip on 12 volt fan that plugs in to the cigarette lighter put the AC blower motor on 2 and the fan will circulate the AC. Just a suggestion. Replacing all the relays and CB won't change the current draw of the blower motor or anything else.

By setting the AC/Heater fan switch to #4 (High speed), within 10-15 minutes the circuit breaker (CB) would blow, cutting off the AC/Heater completely, for about 3-6 minutes before it cools enough to reset itself and fire up for another 5+ minutes before overheating again. The hotter it is outside (and inside) the faster it blows the CB and the longer it takes to reset.
