Hi Loren I've checked for water ingress under passenger seat and its bone dry. 

I already put a new ignition switch electrical part on with no effect. The car alarm sets as it should with no beepsi

ive noticed a  relay under the same seat with the no 53 on it would you say because the alarm works ok that this relay 

would be ok too . Any help is appreciated.

Exactly which ones stay on constantly?  Just the mileage?  Normally, like mine, get in car, insert key in ignition, turn key to position one (not start) and cluster lights up showing mileage, digital speed, outside air temp and oil level count down.  Does yours do that?  If you are actually getting that much battery drain I would find the fuse for the gauge cluster and pull it until the next time you drive the car and until you get this sorted.  I'm trying to figure out the logic of this but need more information.

Mileage/ clock/ digital 0mph stay on constant when I have locked the car. I have it on a ctek all the time I'm not using it. 

When I enter the car the lights are already on( never went out) put in the key turn to position one oil countdown working fine and starts and runs absolutely fine. If I don't use the CTEK trickle charger it will not turn the engine over within 2-3 days. I've had new ignition switch new alternater I've even tried changing the cluster and that did not work either.

That function is controlled by the alarm/locking box and the cluster itself.

You will likely need a PST2 or PIWIS tester to do a diagnostic check on both - as well as checking for fault codes.

If you do not have access to one of those then you will likely need the assistance of a shop that one.
