I recently replaced my mode switch, blower motor, blower motor relays. Circuit breakers, and vacuum solenoid for the center vents. On max ac, I get the center vents to function, but if I switch it to vent or heater, the center vent closes. ??? On my other cars on the heater & vent settings the center vent stays open, but not on 16851 (the one I'm doing hvac work on) Also even after replacing the blower motor, fan speed relays, new circuit breakers, I still have no 1 & 3 fan speed? And ideas on the center vent issues and the two missing fan speeds? Thanks, Joe O'Brien 2524, 16634, 16851 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
