I’ve checked all the fuses, yes the window still roll down when you engage the button to put the top down, never been driven on salty roads been parked in the garage for the last year and a half that I’ve had it, I’ll check the hydraulic fluid and filled it and still nothing! I’ve check the switch on the passenger side top and I don’t know where to go from here, maybe it’s time to just sell the car 😩
This is just too much to diagnose remotely. Let's take some of it apart:
1) The power seats are a SIMPLE system, devoid of any electronics, they are simply electric motors run by a system of switches and relays. The most common issue is the little circuit on the "Power Seat Relay" that suffers from fractures in teh solder on the parts on the board. A new seat relay costs around $30 and plugs in. I don't see how power seat issues are related to anythign else.
2) The door locks, lock-unlock and top issues are likely related to one another. This is where the idea of a new battery enters the picture.
Also, one would perhaps want to question WHERE this car was stored. Did you have it in a horse barn? (I'm not being snotty.) We've seen 'barn stored' cars with chewed up wiring, thanks to the rodents that bunk with horses or cattle. If this is the case, burn the car with fire and file for insurance. (Seriously, some here will be willing to help you, not me. Life is too short, sorry.)
Is there ANY chance of water intrusion in the rear wheel wells or trunk area?
This would explain every issue other than the power seats (and I've already said I dont' see the power seats being part of the rest of this). Tear the liner and trim out of the trunk and look for water intrusion in the wheel wells and trunk cavities. Just verifying that there IS no water damage would be helpful. WHile in there, look for chewed wiring or rodent droppings. If you see signs of urine or droppings, remember, suicide is always an option - way easier than fixing rodent damage.
If you can't find any of the above (no water, urine or droppings; no chewed wiring), we have more detective work to do. If all this has one cause, and it is not rodent or water-damage related, this is going to be something so simple it's going to make you mad in the end. Problem is, getting to that end may be a long, frustrating task. But fact is, it will turn out to be something stupid.
