The local Mr. Goodwrench service dept. worked on my wifes car, and ever since it has had water on the floor. We found out they cut back the flooring under the carpet and ruined part of the seal to the housing. What can be done since they used black RTV sealant to put the housing back on. I am told by another dealer that they must of had a monkey trying to fix it because they did not know the correct way.

Take it back and have them fix it! If the service rep gives you a hard time, talk to the service manager for that dealer. If you get no satisfaction, take it to the reginal manager for General Motors.
Mr Goodwrench didnt get to be as big as they are by not treating customers with respect, and standing behind their work. If it is something they messed up, I feel confident that they will correct it.

I use to work at a dealership, if the service manager doesnt help you insist to speak with the owner of the dealership that usually does the trick also

Since GM has no repair parts to correct this problem, and GM will only give me a trade in on the car that the service dept. ruined I am out of options. I called the regional rep. and they stated that I was out of options also since there is no way to correct the problem! I will not get a refund unless I take them to court. I was hoping to save the car since we get over 30 mpg. from it. Not only did we go to the regional rep's, but we went to the higher ups from GM, and they were the ones to offer $5,000.00 off a new car.
We were hoping that someone knew of a way to seal this up so we could keep the car.
Thanks for the advice.

So If I understand you correctly, they cut away part of your flooring to repair the A/C system, and now the patch they put on the floor is leaking? Or is it the A/C system that is leaking?
If it is the floor, then take it to a machine shop or somewhere they might can tach weld a piece on the bottom of the car to cover the area. Then you can seal the edges with weather proof RTV and maybe that will fix it.
If it is the a/c system, or ducting around the evaporator, then you might can go to a junk yard and find pieces to replace what is bad.
Not really sure of what is leaking, or why they would cut your floor to fix it.

When the service tech "Mr. Goodwrench" took the housing off he also cut the flooring pad out for some reason. The floor pad is rubber on one side and sound proofing on the other. The gasket to the housing goes between the floor pad and the housing.
The housing fills with water and seeps through another cut about mid ways up from the bottom of the housing against the front firewall.

Is there no way to get in there and RTV the mating surfaces and try and stop the leak? If this is the housing for the evaporator drain, I would think you should be able to take it apart and seal the heck out of it to keep it from leaking.
But I cant see what you are up against, so Im not sure how hard it would be.

Suggested Repair

Have the dealer that cut the floor pad and disturbed the housing gasket correct the leak, escalating to the service manager, dealer owner, or GM if needed. If they will not repair it, reseal the evaporator housing mating surfaces with weatherproof RTV after restoring the gasket and cut floor pad, or replace damaged housing or gasket pieces from a salvage yard.

Conversation Summary

An Oldsmobile developed water on the floor after a dealer removed the A/C housing, cut the rubber floor pad, and resealed the housing with black RTV. Water collects in the housing and seeps through a cut near the firewall because the gasket no longer seals between the pad and housing. Advice was to demand a dealer correction and, if that fails, reseal the mating surfaces or replace damaged parts from a salvage yard.
