Oldsmobile/Buick Repair: 1996 Olds ciera - a/c blower, vacuum line, wire connections

Question
I had a tune up on my Olds a year ago.  When I picked up the car the a/c blower didn't come on.  I pulled right back into the shop and the mech put up the hood and messed with something and the blower came back on.  Since then, it has been going off intermittently for a few minutes and then comes back on. Now it's been off all day...Can you tell us what to do.  If it's just a wire, we can fix it but don't know where to look.  It's hot here in TX. Help!

Answer
What mechanical work or ANY kind of work has been performed on the vehicle recently ?. As most problems that occur after a recent repair was made can be traced back to the area of where the repair was made as a vacuum line may have been knocked loose or a wire connection came loose, Look around in the area where work was performed.

There are numerous possible wire connections in the engine compartment try manipulating some on them.'
