I will be offering repair services for the FC wiper switch. This is a common issue on all FC models. The main symptom is only one speed will work for the wiper motor , or none at all. The issue that will cause this is an onboard relay that goes bad, so the unit will need to be opened up in order to replace the relays. The price covers the work & shipping back to you. 
The clean'est way to do it. 
 
**This is a ship in service. Please send switch without knobs , they will not be needed for the repair. You will need to ship the switch to the PO BOX address [ 215 S MAIN #117 , PORTERVILLE CA 93257 ] located at the top of the website. 
 
** I will stand by all work performed at GeeSpecAutomotive. Warranty is good as long as you own the vehicle. If you have any issues at all with any of the services or products reach out & let me know so we can fix , repair or help diagnose your problem. Even if there is user error at play , i won't leave you in the dark. Im here to help you help me help you.
