When I try to lower my passenger side window from either control, it makes a soft click and nothing happens. I have gathered from other posts that I likely need to replace the motor and links. My question is: is this within the realm of my limited experience to undertake, or would I be better off taking it to a professional? Thanks!
If you do a search you'll find this is very common. The pass window doesn't get used much. The remedy.. bang on the door while operating the switch. It usually jars it loose. Then use the window once in a while.
You could also have a defective relay in your Right Door Control Module RDCM . The contacts in the relay get burnt and do not allow enough current to pass through to allow the motor to work. Bang or slam the door can and some times that will help.
Also try grabbing the wires inside the rubber accordion tube between the door and door frame and giving them a good shake!
Carry out each one separately so you know what one helps.
Very easily doable by yourself. I have NO mechanical experience and I replaced mine easily. Ordered my replacement part from Gene at www.gmpartshouse.com and used Vette Essentials website for door panel removal instructions and here is their link: http://www.vetteessentials.com/instr...or_handle.html.
Take your time. Be very careful removing the door panel as you can break the male connectors off from the door panel itself (ask me how I know) and replacing the door panel is VERY expensive unless you get lucky and have the time to wait around for a used one. Also, with your new window regulator assembly, there will be an odd star shaped zip tie holding the cables in an X pattern. Do NOT cut that zip tie. It is used to help secure the cabling to the inside of the door panel. Be sure you test the functions of your speakers and door panel buttons (windows, door locks, etc) to make sure you reconnected the wires (ask me how I know).
Sort of weird, but what Todd157K is true ... something seems to get stuck. Banging or driving around will probably fix it. Preventative maintenance is rolling the windows down and up every once in awhile.
The "Fonzi" method worked for me too.
Turn on key, open passenger door, hold down window button, Pound the **** out of the lower, center inner door panel. Mine took about 10 - 15 hits.
I tried shaking the hell out of the wires, which didn't help. The 'Fonzi', however, worked with just 2 hits. Thanks for the advice! Hopefully I'll be able to get more window down/ top off time now that the temperature is below triple digits...
open the door all the way and then see if it works, sometimes you get bad connections in the wiring between the door and body and opening the door gets things working again... happens to me once every couple months...

Glad it worked for you too.
Never under estimate the power of percussive maintenance.
Wow - I can't thank you guys enough. My passenger window on my newly purchased C5 (1999 Coupe, with 25K miles) was inop, and I was afraid I'd have to purchase a motor or something - a couple of thumps to the door and everything's working great now! What a fun car to drive - with the 6-speed tranny, heads-up display and the Bose cranking, it's a blast. We drove it on a trip a few weeks ago from Johnson City, TN to Charleston, SC and on to Hilton Head Island, SC - got 31 miles / gallon average on the whole trip. It's my little economy car!

Beating on it may work for awhile, but eventually you will have to replace the window regulator assembly. I thought that rolling mine up and down periodically would keep it working, but it finally quit working completely. I installed a new assembly and it worked immediately, so it was not a relay or bad connection.
I have the same problem with my pass. window, I do the Fonzi method its work for awhile and it quit,,,so I have 2take everything off and pound on the motor again and it work but a week after that it quit again. anybody have some idear...or else..

I am speaking from experience. The Fonzi method IS NOT a fix. It only delays the inevitable. I used the Fonzi method for nearly a year before that no longer worked.
If you hear a clicking sound when you depress the window button, but it doesn't move, you need to replace the motor/regulator assembly.
I also had the same problem but the dealership got me for some serious change for a loose wire. The plug had come loose, but it took a complete dash removal (or so they said) to find it.
I thought my car did it today, I haven't tied the knock knock thing yet as the cars already put up. I do have a theory (maybe its been brought up already). The window uses relays, one for up and one for down. The relays that GM uses are notorious for being cheap and sticking. My wifes GTO wouldn't start one day and it was because the fan control relay stuck on and the fan stayed running until it ran the battery down. After jumping the car the fans were still on so I took the relay out and tapped it on the ground and low and behold it fixed the problem and it hasn't happened since. I wonder if this is just another case of cheap relays and the hitting the door frees the relay, nothing to do with the actual window or motor, just one more theory.
I think I am going to remove the door panel gently to make sure the window stays locked up and tap each relay to see what happens.
Well when I went back out its working fine.

The hardest part of the job is getting the door panel off without breaking any of the mounts for the nylon fasteners. Getting the trim plate off from around the door handle was no easy task the first time either.
Once the door panel is off, the mechanical part of the job is easy.
