... How can I determine if it is the vacuum switch, selanoid or the motor.

The Pressure switch tells if the blower is working and vent is clear. Use a manometer on the hose while the blower is on and compare to specs. Alternately, to manually test, remove the hose and lightly blow / suck into the pressure switch. You should hear a click. Remove the wires and test for continuity before and during the previous test. If the results of before and during do not change then the switch may be bad. You would still need the results of the first test if the pressure switch passed a manual check.
The temperature switch should have continuity. It only opens if the blower housing gets too hot.

There appears no way to separate the motor from the fan housing to purchaes the motor only. Looks like the motor and housing with the fan have to be purchased as a single unit. I would just like to replace the motor everything else seems to be working fine.
Did the blower ever start? The water heater worked for 7.5 years with no issue.
Did the burner ever light or try to light? When I swapped parts I took the part from the non-working unit to the working unit next to it. The parts worked in the functional unit so I did not swap back to the non-functioning unitl. Only thing that did not work was the blower motor.
Did you ever get a error code from the gas valve? The gas valve does not have any error code read outs.
Do you know where I could but a replacement part, blower and motor?
If we could get the blower housing apart the motor is built by Jakel Incoporated, number 110533-00, 120V, 60 HZ, 2.3A 3000RPM Thermally Protected Class B INS
The water heater is a Bradford White Model MITW40LGBN12, S/N AD4553568.

I mean do you have a source for me to purchase the vent fan for my water heater?

Edit: I should have said the entire fan assembly is one unit, not nessesarily the whole top. Sorry.
