Doors have to be closed for the windows to work and if the lights turn on the fuel meter won't work and as soon I open the door and put the key the a/c LCD the speedometer lights and flor lights start flashing

Happened Weds, 1st time wouldn't start when I came out of store; got it started after 20mins, then it stopped when idling at red light, kept trying until 45 mins later it started again. Shut off when got home. 3-4hrs later my brother came to pick it up, it started, but stopped again before he could get it to mechanic it stopped again. Pushed it to mechanic; mechanic says not fuel pump and problem has not happened again in the 2 days he's had it.

Tune up a month ago.

Already replaced brake pads but the brake warning red light stays on and the low brake pads keep logging on every time I started the car. Need help please.

A/C works but the drivers side blows hot air wile the passengers side blows cold air. It has R134a, what could be the problem? Stuck actuator door? Please help, it's summer and I live in Miami...

stops after 6 or 7 ticks

Is there a mechanical bypass for this electronic function?
