You mean without downloading the blockchain?
Download bitcoin core, open bitcoin-qt (yes it will start downloading the blockchain), close it, copy the wallet.dat to %appdata%\roaming\bitcoin (or wherever it puts it), reopen bitcoin-qt, go to help->debugconsole, type "dumpwallet walletdump.txt", go to the bitcoin folder in your program files, and find the walletdump.txt, open it, there you will find all public keys, open electrum, create a new wallet and choose "watch only", type the public keys from walletdump, and then you'll see if there's anything in that wallet.
send them to me and i can do it
