Blown A/C Fuse

I was wondering if anyone had any thoughts about this problem I'm having with my a/c. I just took the car to the dealer and was very excited to find that they could recharge the system with R12. I was however disappointed when they told me I needed a new climate control unit, around 630 dollars. Here are the symptoms: when I press the a/c button the 7.5 amp fuse to the climate control blows. When the compressor won't start, i.e. I take the relay out or prior to the the system charging (meaning the low pressure switch would prevent the compressor from starting), and I press the a/c button the climate control responds by adjusting vents and the motor reacts. I suspect a short but I'm not sure where to look. The dealer said that they jumped the compressor and cold air started to blow. I haven't replaced the relay yet, that's next. Any thoughts would be helpful.
Thanks,
Matt

May be over simplistic, but the second cooling fan comes on when you turn on the AC. My second fan seized, and everytime I turned on the AC, it burned the same fuse. I replaced the fan with an updated 6 blade fan, and everything has been cool ever since...pun intended..I hope this helps......

Thank you very much. That was the kind of tip I was looking for. Never would have thought of it.
