On hot days my AC turns on and off randomly for the first 10 minutes usually. When it's on it's very cool so I don't think it 's freon and I put a gauge on it and it had plenty of pressure. After it stays on it will freeze me out if I let it.

Any Ideas?

What is your low side pressure both off and running? Also what is the ambient temp when this occurs? If possible how about high side pressures? All measurements should be takin when the system is acting up.

Sorry, don't have access to a gauge anymore, but I think the low pressure side was 30 psi running at about 88 degrees.I don't think it has anything to do with the charge.

I misstated the problem I should have said my FAN goes on and off for the 1st 10 min when it's hot outside. The cooler it is outside the less the fan acts up.

If your reffering to your blower motor in the dash it likely has a bad blower amp.

Where would the blower amp be located? Did some reading and came up with a part# 27761-70T03 does that look right? I have the nav package and automatic temp control. Is the amp the same as the resistor?

Thanks for your help.
