Question A/C, hot in one vent cold in another

For some reason my 93 SC400 is blowing cold air out of the passenger vent, the center vent is cold on the right and warm on the left half, drivers side is warm. Can anyone explain why it would be doing this and how it can be corrected? I just got it back from having sparkplug wires put on at the dealer if that helps to locate a wire or something that could have been knocked off.
Thanks,

An update for those who have interest, I took it to the dealer to diagnose. They found through a leak test with dye that the a/c pump seal was out thus leaking compressor oil and freon out. Now I know why all that oil was all over everything in that area, thought before the oil filter was dripping . Anyways, one reman pump, one a/c clutch (due to the 116k miles), one hose, one receiver, sum evac, pump oil, and R12 later I get to pay them $1500 plus tax including labor to r&r. :eek:

You will appreciate it in the summer though.

I have the same problem, warm from one vent, cold from another. So, was the problem leaky compressor?

Yes it was. As time went on, before it was repaired, all vents would blow warm air.
