As for what size fuse; I believe I would use a 20 AMP.
The FSM does not state what size fuse to use. The window CKT is protected by a 30 AMP CKT breaker. That should be for both doors unless there is a second CKT breaker I am not seeing. So the motor itself should not draw more than 15 amps in that CKT (30 divided by 2).

Luckily semi-retired & Corvette is not DD.
Want to focus on Power Window Control Module before motor.
I suspect the PWCM because I did an interior light dimming test & they did not dim, which semi-clears a stuck/bad motor.
& I hear a click in the dashboard when I release the switch from holding it in 'down' position. Click seems to be from approx. where PWCM should be.
Can the PWCM be got at without having to pull dashboard apart??

just a guess but could be the window relays in the door module if you can solder you can fix your self below is how to remove door panel, also you could swap modules to see if its bad relays....could be some threads on repair, so a search would also help

Oh, this is going at a glacial pace as I have a large 'fix this around the house" list.

Hi Polo Vert
Would appreciate some guidance as regards disassembling the switch assembly.
I have had a good look at the unit, which resembles a large black plastic match box, with a wiring module attached. Looks like you have to get a fine screwdriver under some clips?, or something like that. Can't see any obvious screws to undo.
Thanks
CVT
PS - once opened is it easy to get around in there or are there springs that have to be caught before they take off?

If you follow the troubleshooting procedure from the service manual you will find the fault in the system. The manual was written by the people who designed it.
I believe the door control module is behind the dash next to the radio. The check for that item is last in the troubleshooting procedure.

Sorry for not replying sooner, haven't been around much recently. I took a set of those really small screwdrivers and carefully popped the box open. No big surprises in there but there are some small pieces so make sure you take it apart on a clear bench/table. Kind of a PIA but not a hard job. Patience.....
Am I correct in assuming that if I get the box popped open I can disconnect the wires from the switch connector 'blades' they slide over?

I pulled the switch assembly out of the door and had all the wires off then took it in to my work bench before disassembling.

Did you take that plug block with wires out of the switch as 1 unit, or did you just pull each wire out of the back of the 'plug block' while it was still hooked into the switch assembly??

It looks to me as if the wires are in a plastic plug block that plugs into the switch assembly.

I can't remember the exact order but I do recall having to pull the buttons off of the rocker switches. These may be helping to hold it together, not sure. But it will all come apart, just be careful and patient.

Still not convinced or just curious of how it works?
If you do take it apart remember to take some pics and post them for the future troubleshooters.
Let us know what you find.

Previously I just exercised the switch and it would work fine for a few weeks. I took out the switch to see if I could make a more permanent repair. I did not get the switch apart so I tried spraying some WD40 into the switch from the openings in the bottom of the switch assembly. I worked the switch some and blew it out with air and let is sit for a day or two. When I put it back in it worked like new and still does a couple weeks later.

Due to switches age & other work I will have to do if I pull the door panel, (it is coming away from inner frame), decided to put a new switch in to upgrade that part & eliminate it from the ?? list.
Should be here by weekend.
If that doesn't do the trick then I'll just work methodically through the manual's diagnostic schedule.
I'll pass on what I learn.
