My first guess is a loose connection, likely at the battery.

Please post generation specific questions in the appropriate forum. I'll move this to the MKIII section

k have cleaned all terminal cables tried lil locked n unlock thing put diff battery n still only get a single click from behind glove box when try to start it used to start n nuetral when actn up now nothing like to fix today but lights are not jumpn around nemore since cleaned and where can i look at schematics of this car for free to get wireing diagrams or locate specific parts on this car

Well, if all connections are good then I would pull the starter, take it to an auto parts store, and make sure that it still functions properly.

Check out these two links, they can be very helpful in diagnosing and repairing problems:

MKIII TSRM (Online Factory Repair Manual)

MKIII TEWD (Online Electrical Wiring Diagrams)

Other useful and informative websites can be found in the MKIII FAQ section on this forum

could that be the main relay??
check your car for error codes!!!!
