Rear A/C switch

I need help can anyone tell me where I might be able to locate a rear A/C switch for my 1997 Safari? Help in live in California and my kids are overheating in the back! I know go to the dealership and order but can anyone tell me whereelse I can look.
Thanks, Cindy

If the rear A/C is an aftermarket unit, you'll need to go back to the manufacturer or have someone familiar with the circuits wire in a replacement switch. If the rear A/C was factory installed, unfortunately the dealer is probably your only option as aftermarket companies such as NAPA may not offer it as it is not a "fast moving" part.
