1992 Lincoln Town Car Wiper motor circuit breaker - working

Electrical problem
1992 Lincoln Town Car 90000 miles

My wipers stopped in the up position (common problem from the forum). However, when I reached down to check the fuse (turned out it was more of a circuit breaker or relay instead) it was so hot I had to grab it with a napkin so my fingers didn't burn. It is a rectangular metal piece about 1.25 " by.375" by.625" with two tabs set off center extending another.375".

My questions are: 1) the part number D9AB-14526-CA, 8.25 Amp, does not seem to show up anywhere on the web. I called the Ford dealer and they can get one for me. Before I buy it, I wanted to know if you think that will solve my problem or whether I should be replacing the wiper motor instead as suggested throughout the forum. Also, is the high heat a normal failure mode for this type of device? 2) Do you know where I can order the circuit breaker online instead of going through the dealer if it turns out that I do need to replace it? ? 3) Is there an easy way to test to see if this old one is working right or should I just replace it?

Thanks for the help! Jay
