03 H2 A/C quits

[wrangedog]

Hi,
When I start my H2 the a/c seems to work fine, but after 5 minutes or so it no longer blows cold air. It almost appears that the blower stops blowing. Can the blower motor be going and cuts off as it heats up? I have reviewed the other a/c threads and I haven't found another listing the same problem. What would be the easiest way to troubleshoot this ? I am sure replacing the blower is no cheap or easy task, thanks to all, John
