Window Problems!
I have a 2001 corvette, and randomly during the day, I tried to roll my passenger window down and it just wouldn't roll down. It was earlier that day, and it just stopped, there is no noise/sputtering sound, like the motor is trying to work or anything there is nothing when I press the button. From either door, I was wondering if anyone has had the same problems, and what they did to fix it? I'm thinking its the motor since the buttons on both doors arent working?

What DIC codes do you have?
The remote door lock control module controls the door locks and window functions. The relays can fail but the code should give a clue.

....a word to the wise:
I posted a while back that we should all use our windows, regularly. Otherwise, this type of thing WILL happen. I power my windows up and down, three times a week and have never had any issues over the last 11 years.

Yes. there's an individual relay for each function. Here's a picture of the door lock control module stripped down.

The door control module codes are in the A0 and A1 sections highlighted below.
Corvette C5 Codes
The codes which are displayed on the Drivers Information Center (DIC) are called Diagnostic Trouble Codes (DTC). Each code has a prefix letter followed by 4 numbers and a further letter. After a fault has cleared and the car has run a number of ignition cycles without the fault present, an "H" suffix for history will be set. Anything which is still has an active fault will have a "C" or current suffix. It is possible to see the suffix HC which can be set with an intermittent fault.
To enter the diagnostics mode turn the ignition key ON but don't start the engine. Clear any DIC messages (such as Door Ajar) by pressing the RESET button then push and hold the OPTIONS button and press the FUEL button 4 times.
Once the diagnostics begin the computer displays the codes which have been set since the system was last cleared down. It will visit each of the 11 sections in turn and cycle through each code (both H & C) every 3 seconds. The list displays in the following order:
10 - PCM - Powertrain Control Module
28 - TCS - Traction Control System
38 - RTD - Real Time Damping
40 - BCM - Body Control Module
60 - IPC - Instrument Panel Cluster
80 - Radio
99 - HVAC - Heater, Ventilation, Air Conditioning
A0 - LDCM - Left Door Control Module
A1 - RDCM - Right Door Control Module
A6 - SCM - Seat Control Module
B0 - RFA - Remote Function Actuator
Write the codes down for reference because often you’ll want to reset the codes to see which return.
To clear the codes, wait until the computer has cycled through every section. Press RESET to enter Manual Configuration. If it shows a code, press and hold RESET until it displays "NO CODES". If no fault is present in a particular section it will already show "NO CODES" or "# CODES". Work through each section until you clear the system. Turn the ignition switch OFF to exit diagnostics mode.
U codes set when there are power interruptions and are often present and generally are nothing to worry about. They set when you have battery issues or you change batteries but if you have power gremlins expect to see U codes. If you have done the DRL mod or pulled the A2 fuse expect to see B0502 and B0507 codes. If you have an after-market head unit the Radio section will display “NO RADIO PRESENT”. The computer is looking for the OEM devices and
Now drive the car for a short while and any current faults will be reset the DTC

The Vert cycles the windows every time the top comes down. I've never had a problem there but the door lock function has failed twice.

So when I go through the DIC I should look for B2275C if it isnt working or is at fault? and if it is just a fuse would it show up on my DIC? and if it ends up being just a fuse, where is the door lock control module?

I've had this problem on my vert before and you get no codes. Just bang on the passenger door armrest until that eventually doesn't work any more and then get a new door module.

Did you ever get this fixed? Mine would stop working sometimes and I figured out that if I held the button for the window to go up or down while I hit the middle of the door panel it would work again. Sometimes a forceful door shut would make it work again as well. After dealing with it a few times I took the door apart and figured out which of the connections was for the window. I assume that one or more of the pins that is supposed to make contact in the connection had become bent over time. It was just enough that if the door closed just right or the car went over a bump the contact would be open. I used a small screw driver and bent all the pins slightly to the direction where the contact should be made and put a dab of dielectric grease on them. No problems for over 6 months and it used to be a weekly problem!

Does using my window valet to lower/raise the windows also help with this preventive exercise or do I need to use the controls on each door panel?

Using the window valet seems to work. If I leave my car parked for an extended time without using the windows, my passenger side window won't go down until I give the motor a rap.
I have been using my window valet often and haven't had the problem occur again.

I have this problem with my Chevy Colorado truck. Especially when it is hot. It will stick in a position and if I hit the door it will move until you let off the botton and then it will usually stick in that position. Most of the time it will work as normal on a cool morning. I was told to replace the motor. Is that true or is it some relay or module? It does have remote door locks.
