Quick wiper question!

my wipers only work at one speed. and they work great at that speed..
Is it the switch thats bad? or a module? i dont think its the motor because it works great on that ONE speed! :eyes:

is it possible to change out the switch or do i need to yank the collumn?

I had this issue on my 96. Replacing the MFS fixed it for me.

Could be the MFS or the intermittent wiper module in your case though, I would do a little debugging with some spare resistors and a multimeter. If it's the switch, in your case I think you are going to need to pull the steering wheel so you can get those round housing sections off, but I'm not sure, one of the Renix/pre-94 guys will know way more. (Assuming this is the 89 trail rig in your signature)
