Unhappy Need help indentifying MFG of dual pane windows

I am trying to determine the manufacturer of my dual pane windows. I need to replace some to sell the home, the seals have broken. All I can find in the window is a number of the form: MD234HM664X where the '234' changes on the size and shape of the window, i.e. MD226HM664X, MD228HM664X, etc. The home was built in Boise, Idaho, in 1990. If you have any idea on how to identify them please let me know.

They DO NOT have the numbers Andersen says they should have. Milgard says they are not theirs, wrong model numbers. CertainTeed uses a sticker which is NOT there!

If you have any idea please let me know.
thank you,

Dual pane glass does not have to made by the maufacturer that made the window. Any dual pane glass can be used to replace the ones you have. Many times the manufacturer of the glass and sometimes the window can be found on the spacer that separates the two glasses. It is usually some abbreviation of the manufactuers name and date of manufacture. (example RWC - 02-95)

Double pane glass can not be repaired. It will need to be replaced with a new factory sealed insulated glass unit (IGU). Contact several small window repair companies in your area for estimates. If window frames are still in good shape, you can usually get by with replacing IGU and not entire window. IGU's are sealed in the factory. A new IGU can be installed in the existing window frame. If you were staying in the home, it would be advisable to replace windows with a brand that has a lifetime warranty that includes seals. Whatever warranty you get should be passed on to new homeowner if allowed. Some warranties are nontransferable.
