The AC fan in my 96 GMC Yukon cuts on when I start the vehicle but after an hour it shuts off on all speeds...any help?

Need a faster answer?
Check the connectors to the AC blower motor switch and the motor itself, see if they are burnt/discolored, replace as needed. Also replace the blower motor. The repair connectors are available from the dealer.
