Part number?

[Sal Lubrano]

I need a new seal for my A/C Heaterbox. When it rains I have water comming inside down the carpet on the passenger left side. Can anyone tell me the part number so I can order it from GMPARTSDIRECT.
Thanks

I would like to help, but I need more information. Are you talking about the seal between the case and the evaporative core (3039245), or the seal that goes over the heater core tubes (3037635)? Or are you talking about the gasket that goes between the inner most case and the firewall (3042381)?
There are other seals involved that look to me that any weather proofing seal would work on, and they have no number.

I got these numbers from the GM 44W book.

I am not even sure about which one it is myself. I thought it was only one seal that kept the rain out. Thank you for the part numbers. I will have to check out which one is bad.
