I hear a sort of click noise when the A/C is switched to Max A/C mode. I just had the blower replaced at the dealership but that did not help I was wondering does anybody know what it could possibly be so I can take it back to the dealership and show them what to look for.

 

Hello autiger72 and welcome to FTE

What type of vehicle are we talking about? That click noise is probably the door closing so that only cabin air is circulated or the switch itself.

Was the blower replaced because they thought it was making the noise?

 

It is a 2003 Ford Explorer and the blower was replaced because they thought that was the problem. The clicking noise is all of the time. Not just one time

 

Sorry I missed your title.

Your problem is a horse of a different color. Does the noise change when you change blower speed? It only does it on max AC correct?

This is a new one on me.

 

I am taking it back in the dealership on THursday. Yeah the noise gets louder. I think there maybe something in the recirculation is broke and is flapping around in the Max A/C only. Yeah on the other setting that are not the reciculation mode it is fine. It is only in that Max A/C mode.

 

The clicking noise may be the low pressure switch cycling. The new Explorers have a new AC compressor that appears to be too large. My 2003 Explorer AC cycles on-off every 15 seconds when driving over 20 mph, even during 95 degree days and with a hot cabin. Ford replaced every major part except the evap coil and refrigerant lines. Ford finally said they have no fix.
