Afternoon folks! Just noticed that the recirc button on my '06 AV does not increase the fan speed like it used to and the fan is definitely not blowing as hard as it used to. Any suggestions??? Just under 135K miles with no AC issues in the past.

Thanks!

Recirc does not increase speed.
It just draws air from inside and makes it more noisy....

 
Thanks ygmn! In that case I guess a flapper in the system is not working because it is definitely not any louder with record on. Any ideas what to check?

Thanks!

Actuator is very near blower motor...

Remove blower motor and check it out.
 
Thanks! I will check it out. Are they vacuum or solenoid actuated these days? Cables were so much easier....
 
what if the blower suddenly stopped working while running errands and now won't turn back on?
I have changed the blower motor and the resistor and or relay. and it still won't turn on ?
 
pcaccatino - Might be the climate control module. Check to see if you get power to the blower with a volt meter.
