Default Cooling fan relay DBC11617 refurbishment?

I went for a drive in my 1994 XJ40 and noticed my temps went passed the Normal. I kept it cool enough to get home, noticed the fans werent working so I accessed the Green Relay. I gave it a few taps and its back to working fans. Ive reflowed the solder on a couple of relays in my XJS with success, so Im just curious to know if this relay can also be refurbished?

If you can open it up, why not give it a try? Also - the sensor in the rad is also a suspect ...

I should replace that sensor. Is there a part number that I can use? And just to be sure where the sensor is located. Is it the one on the left side down by the hose? One of the tests I ran, was turning on the AC and the fans did not come on. Once I messed around with the relay, the fans did work. Im suspecting the relay since, it has been wet and cold lately. I drove the car in rain last, and that relay gets exposed to a ton of water. The other thing I noticed was that the relay looks a little puffy at the seams, so someone has messed with it before. Perhaps the moisture has been getting in. Is it possible to relocate the relay to a higher, more accesible location?

The sensor is the only thing with wires emanating from it in the rad AFAIK !

But, just to be sure, check the part number here:
