High Beam Issue...

So i replaced my Multi-Function switch once on my 98 GTP because the hazard switch didnt work and everything was fine for a while... Then one day i went to switch my high beams on (mind you they worked after i changed the MFS) and i get nothing but my parking lights! Also the high beam indicator in my dash cluster is on but VERY dim on low beam and its on on high beam. Also the high beam indicator on my Heads-Up Display flickers about 50 percent of the time regardless if i have my high beams on or not. I changed my Multi function switch back to the old one that i know works and that didnt help at all. The bulbs are only 3 months old and that wouldnt cause my dash issues so I DONT KNOW WHATS WRONG!!! HELP please. :banghead:

Here is what I would do. It looks like a possible short in the wiring from the output of the MFS to each headlamp socket. Pull both headlamp bulbs out. Then at the big connector block under the dash for the MFS and the ignition switch disconnect the electrical connectors to create an open circuit. Then with a DMM go to the lamp sockets and measure resistance to ground. Let me know if you need the pins and wiring color coding. There should be no resistance reading to ground on the meter with the exception of the ground at each lamp socket.
