AC blows cold but not hard enough to cool down the car what gives? So my ac blows cold and all the speeds work but it doesnt blow hard enough to keep the car cool even with the ttop shades and tinted windows.Without buying a new blower motor could the blower motor not be getting the correct voltage and is there anyway to give it more voltage to get more fan speed without frying the motor?

You may have a vacuum leak and the vent doors inside the dash aren't opening all the way. Check the A/C vacuum lines over by the PCM under the hood. Check the plastic black "T" fitting as well, check for small cracks, they get dried out over time. I think they cost like $5.00.

Thats what i was fearing because it blows cold but not enuff to feel like im going to freeze unless its night time and not as hot out then i have to turn down the ac but during the day it sucks but i dont want to drive my wifes suv so i soldier on its just really freaking hot

Simple test to see if you have enough refrigerant in the system. Buy a thermometer for $1 from an auto-parts store and stick it in the vent. If it reads under 50 degrees, (45 is the best you'll get) while you're driving around, its fine. No matter what the fan speed is, the vent temp should remain the same.
If the blower is not blowing hard enough then you may want to check the blower motor resistor. It controls how fast the motor turns. I had that problem in a 2000 Grand Am I owned, the blower motor resistor was partially burned out and would only operate the blower motor at med-low speed.

that sounds like a reasonable question. check one, check the other. figure out whats good so you know it's not the problem. In this case looks the blower motor is cheaper then the resistor based on what I just looked up on Autozone.
