Default '03 Suburban a/c blower

I just replaced the compressor,drier,orifice tube,11 oz of pag oil,3lbs freon 134a, belt and tensioner and fan clutch and suddenly the blower in the front of our Sub wont blow on high and stays on when I take the key out. Eventually it goes off. Any clues?.

I see you already did. Check my post on your old thread.

Cool Fixed!

A/C blower module. Got a deal on it $92. I'm into this repair for close to $500 now and think it works better than it did when it was new. I also sprayed the water hose with a nozzel inside the evaporator coil box(while I had the module and blower off) to wash out any dirt,and also cleaned the blower wheel of all the dust that was on it too. 95 degrees outside and getting 29 degree air blowing up my shorts.

PS- an Autozone near me loaned me a vacuum pump with a deposit on my credit card.

If you really are getting 29*F air at the vents, then on a humid day, you'll probably freeze up the evaporator.
