I have owned my 99 4runner SR5 for almost 3 years now and this will be my first issue with it. I took it through the automatic car wash and water started coming out of the corner of the dash blower fan housing, onto the passenger floor mat, i tryed sliding the control to recurculate then it stopped. Ive always took it through with no issues, i did stop when blow drying on the windshield/cowel area longer than usual, could the pressure from the blower going into the cowel damage somthing? Does anyone know what the heck is going on????

 

A/C drain hose is clogged,blow it out with compressed air or coat hanger(gently).
