Greetings folks.
I cant get to the shop till after Thanksgiving the indys are slammed, so while I wait I’d appreciate some help. Frm is 2 years old bought new from fcp. Electrical issues started mid drive. Since then Ive replaced the battery and registered it, replaced every single fuse in the junction box and 1 relay. The car fires up just fine. Headlights, tails good. But

Car 2011 335i manual
Windows don’t work at all (sunroof works)
Mirrors don’t work (reverse tilt works after about an hour of running)
Car wont enter sleep mode - hazard switch flashes, start stop button remains illuminated
No cluster illumination (until 15m-1hr+ of running)
Cluster brake amber stays on when ebrake is down
High beams/fogs dont work (until 15m-1hr+ of running see below)

15m-1hr+ later of running these work until the door has been open for 2-3 minutes, close the door the items listed start to happen again.
Hazard light stops flashing
Cluster illumination comes on
Interior lights work (glove light and trunk light always work)
Signals work
Break lights work
Adaptive headlights adjustment kicks in
Fog lights work

Update
Since I have time to kill I let the car idle for awhile before hopping in to test.
When the hazard switch stops blinking protool will show the frm.
Driver side controls still mostly dont work. I can move the mirror right and down but not left left or up.
Passenger window controls zero function.
Protool does register input on both for “open” but not close despite nothing happening.
I did manage to get my passenger window up very slowly activating in the app. Slowly meaning the function worked maybe once every 10 activations.
No short circuits registered in app.
When I turn the car off, we go back to original state of issues, hazard switch blinking no comms with frm dome light off etc
