A/C Blower Motor
The motor doesn't work normally, but if I tap it with a screwdriver it will come on. Is the motor just going bad? I cleaned all of the connections and that didn't fix the problem.
Is this what the blower motor looks like? Is $33 a good price for it?
Is the wrench work just a quick unbolt and replace type job?
Thanks for the help.

I don't think it's the blower itself... I'm on my second GM ('02 Express van new, '98 Jimmy) that does that.
A GM service techie said if it's the module inside the case where you actually tap on it. Not cheap. The '02 at first had a loose connector to the blower, which led to the module failure.

No Module on any GM blower motor that I know of. The '98 Jimmy and some of these smaller truck/SUV's - basically thrown onto the S-10 chassis - have the Resistor Pod glued to the inside of the Evaporator Case and when bad, you've got to cut them out with a dremel or a hack saw. Replacements come with a template and a patch. Fortunately, they don't use that setup on the Vette. To be sure that you don't have a power problem, simply check for battery voltage at the blower connector when the system shuts down. If the voltage is there, replacing the motor should take care of your problem. If the voltage isn't there - you'll need to troubleshoot the power supply. Tell us the Year and whether it's Electronic or Manual Air.

How long to replace the 'pod'?

Your blower motor has its brushes worn down to the point they don't make reliable connection to the commutator. That is why tapping the motor makes it run for awhile. $33 is a normal price, and it isn't hard to replace the motor. The motor mounts on a flat plate on the back of the blower housing on the right side of the engine compartment. Remove the sheet metal screws on the plate, unplug the motor and then remove the blower wheel and motor and replace.

I don't know the flat rate but an hour or two wouldn't surprise me. Someone who knows what they're doing could probably accomplish it in 15 minutes. Were talking a small, maybe 2 x 3 inch hole and the new part simply attaches with a couple of sheet metal screws (just like they do on the Vette). If the S-10 Forum is still up and running, you might ask there. Otherwise, the procedure is outlined in the Service Manual.
