You've a few options. One is to buy whatever is available at the parts store and have them test it before you leave. (Also keep the reciept in the glove box, just in case). The other is to buy a new one. More expensive, but that is for you to decide. Finally, you might want to see if you have an electrical shop in your area. Having them rebuild may give you a better product at a good price.

Good Luck,
