If I wiggle the wires connecting my Bluetooth module it will work for a short while, sometimes a few hours sometimes a few days , I have been told that if the module was faulty it would not work at all, I don't want to replace the module and then find the problem persists.

Any Ideas ?

 

Troubleshooting must always involve some experimentation. I would get a multimeter first and check the wires for continuity and the connections for corrosion and any deposits that may spoil your electrical connection.Unless your Bluetooth module is bad you should be able to fix it either by rewiring or cleaning the connections. Should you need a Bluetooth module I would start in a junk yard. You may pull one from a 2010+ Lancer, Ralliart, Evo X, Outlander or Outlander Sport/RVR/ASX for few bucks.
