First, you may be able to rebuild your switch. I believe you can buy "release agents" for Krazy Glue (cyanoacrylite). So read about my switch rebuild first. It will tell you how to remove the switch:

The Pantera vendors sell the switch for approx. $98. The switch is also shared with the BMW 2002, but the BMW vendors sell it for the same price, so better to give your money to our vendors.
A lower priced alternative is available for $71. I don't know if this switch is identical. You may wish to contact the seller and ask for another image of the front.

I believe Johnny Woods, who's also on this forum, acquired a supply of replacement Hazard Switches and sells them for substantially less - on the order of $20. I'm told his switches don't have the same markings but are mechanically identical, and that you can take yours apart and swap the guts over and be back in business for only $20 or so. Again, this is what I've been told, but I have not done this myself. Contact Johnny directly for more information.
