Looks awesome. I really like the woodwork in the cockpit.
In my car, the windows all work fine, the air conditioning is 'au natural' and therefore always works, and if I have any squeaks in the dashboard, I really can't hear them over the motor and wind.
The motorized window could have a few things wrong - motor, switch, or alignment of its operating framework (sissor lift). Check the fuse first and then if that doesn't help, get an expert to look at it.
Airconditioning could just need re-charging. The system may have a leak.
With the squeak, you could tighten some bolts. First see if you can pinpoint the rubbing that causes the squeak.
Its a beaut'.. Happy motoring.
