3) Is there something else that can cause this or rather what is the cause of this to break - just age? The car is 17 years old. The contacts in the relay become pitted and the spring that closes the contacts can stretch and then it does not make good contact. Or the circuit board in there can crack

4) Can I put an 'older' style relay with a fuse strip in place of this one?
I do not think so. Your car has an afterglow feature that the older models do not have. Your GP relay gets a reading from a temp sensor in your head to determine the time the relay stays on, the older cars have the temp sensor in the relay itself.
