A/C BLOWS THEN STOPS BLOWING

What is your question?

MY A/C STARTS TO WORK THEN SUDDENLY THE BLOWER STOPS WORKING. I'VE NOTICED THAT WHEN I TOUCH SOME WIRES UNDERNEATH THE BLOWER IT TURNS BACK ON. THESE WIRES HAVE BEEN SPLICED AND CONNECTED TOGETHER WITH CONNECTORS. I'VE CHECKED ALL OF THE FUSES, I'VE EVEN REPLACED THE BLOWER MOTOR BUT ITS NOT THE BLOWER. HOW COULD I FIX THIS ANNOYING PROBLEM? ANY HELP WILL BE GREATLY APPRECIATED.
