Front Seat Power Adjust problems of the 2007 Dodge Grand Caravan

2007 Dodge Grand Caravan sxt stow n go having several electrical issues. 1. Passenger power sliding door failed, replaced power door motor, lock actuator, and repaired wiring as the wires actually break/snap overtime. Poor design. 2. Less than two years later passenger power sliding door has failed again, & power locks will not work, & I can open passenger sliding door after locking vehicle with key fob and alarm won't sound! cannot get my children in and out of this door without reaching in and pulling up the lever from inside (too stiff, my daughter isn't strong enough). This is a safety issue and researching it online shows that it is widespread. 3. Power seat motor has failed. We have stow n go seating. In order to stow the 2nd row seat you must move front seat to full forward position, then move driver seat back. . . . . . Driver seat is all the way back now (for my spouse) and I cannot move it forward. Gears are broken. I cannot reach the pedals and my seventh seat is stowed! I cannot get my seat back. 4. On passenger side a part below dashboard (I think is related to heating and cooling) fell off. My floor is now wet even after reattaching it. 5. Light galore! my vehicle rotates between check engine, and service tire system warnings. I've had it checked by several mechanics and all say it's electrical.
