dear sirs

i have a problem in my mazda 5 2007 touring, the A/C blower works properly for about 1 or 2 minute, then the blower speed starts to slow down little by litte until stops, after one or two minutes it restart and does againg. the A/C compressor is fine, the resistor module is fine ( is new), the blower motor is fine, i checked directly one hour, it works.

please help me, i live in a very hot zone(wow)
 
Not sure if this helps but there are cases of a clogged drain causing the heater box to fill with water to where it wreaks havoc with the fan motor. Something to at least check although I doubt it's the issue.
