Hello, new to the forum. Wondering if anyone has experienced soap foam/bubbles coming from the center dash vents during automatic car washes? This happens even if the fresh air in is closed.

 

Welcome to the forum...I could see that happening if the blower is on high enough or the volume of soap/suds is high... I know the recirculate uses inside air over but I don't know if it completely shuts off all external air intake...

I personally stay away from auto car washes..I am convinced the chemicals used are the cause of "fogging" or degrading of the clarity of the headlamp lenses...

 

I believe even on Recirc, about 10% outside air is allowed in.
