1989 vs 1990-up Multi-function switch

[kylix.rd]

Does anyone know whether or not a multi-function switch/turn signal switch from 1990-up will work with an '89? From what I've seen they were redesigned in 1990 WRT how the wiper switch works. For '90-up you rotate clockwise through intermittent to lo then hi. For pre-90 you rotate clockwise for lo then to hi, and counter-clockwise for intermittent. If the connectors, pinouts and electrical sematics are the same, I don't see why it wouldn't work. However if any of those are off I can understand why it won't work. I'm just having a hard time locating an exact replacement and the dealer wants $230! I can find 1990-up replacements all over eBay and similar sites... Just no pre-'90 versions, used or otherwise.

FWIW, I think the '90-up design is far more intuitive and have always thought the '86-'89 wiper switch design was silly. I'd rather replace it with a '90-up version if it will work.

I'll probably have to start calling the local salvage yards to see if they have anything earlier than '90.

89 is a year all its own MF switch wise... I have one if you need one.. PM me if so.

Yeah, it's tough to find those 89 switches. I've put 5 on my SHO and they all fail in the same way. Is there any way to reinforce the clip inside that cancels the blinkers?

unfortunatley, no.. I put a brand new one in the SHOWagon, and it broke the next day...
