A/C blows warm air above 45mph
My 98 TJ blows outside temperature air inside the cabin even when A/C is on at speeds above 45-50. Anything lower than that it blows ice cold air. Anyone know where I should look first for problems?

have you checked the system pressure? it might need recharged. it may be leaking somewhere too...condensor, hoses, seals, etc.

Spend $25 and get a refill kit with a gauge.Typically 97-99' Tj's get vacuum leaks that stop the A/C from blowing out of the vents at any load of the engine(higher speeds).If it doesn't switch to defrost vent only,recharge it.
Ok now I have a new problem the A/C compressor makes a ticking/whirling noise sounds like a bearing. It makes this noise whether the A/C is on or off. Am I looking at a new compressor or is there a cheaper way to rebuild it?

Have an experienced Tech check out that clutch. But, I think that it's a vacuum leak. When you get above 45, it's starving for air. How's your idle with the a/c on? Jeeps have cracky vac hoses all over. Start with a bright light and closely examine for cracks in any thin vac. hose. Look everywhere under the hood and underneath. Don't forget to check the hoses that lead down to the front diff. too.
