So I have a 2000 S500 went for my vacation leaving the car for a month sitting in garage. When I came back the issues started so now the door won't open with remote or close as well you need to use the key to unlock them. Trunk won't open by remote, cigarette lighter port won't work, radio screen is dark, car is stuck in park. So battery was dead I recharged it to no avail so I went to the store and get a brand new one didn't help. Engine start no problem. The rear stop lights not working while I press brake pedal. It's really getting so annoying. Tge steering wheel dont come back to the up position too. Do any of you encountered problem like that? I checked all tge fuses they all okay checked relays with multimeter good too. Dont have any more ideas. Looks to me like the car is in armed mode. But I'm not getting a flashing lights to arm and disarm as well. Anyways the car was working fine day before my vacations. I'm getting all of those abs lights and ESR on dash tried to reset them as usual with turning the wheels nothing. Plugged the obd2 scanner only one code that has been there forever which is secondary air pump.

Sounds like I wish I could but the car is stuck in park

Did you check the main fuses under the right carpet using a large test light (like a headlamp bulb)? They don't look like fuses. You really can't do a good test with a multimeter .

Many of the functions that you have lost are run thru the left DCM (Door Control Module).

The battery dies instantly will not charge when I finally got out of park the fan run continuously but now it doesn't turn on anymoreand car overheats so I parked it it's been about 2 months now and now the front end of the car is fully lowered when I start it the front does not raise any ideas I need help before I take it to the shop

I'm sorry, but I am having a great deal of trouble understanding your problems.

"The battery dies instantly will not charge..."
Does this mean that you can't charge the battery with a charger? Or that you can start the engine (how?) and the alternator doesn't charge the battery? Do you mean that if you charge the battery, it goes dead instantly when the charger is disconnected?

"...when I finally got out of park ..."
Does this mean that you got the battery functional and got the engine running, and then the shift lever will not allow you to shift into Drive or Reverse?

"...the fan run continuously ..."
Do you mean the engine fan or the HVAC blower? So you have the engine running and the engine fan runs at high speed? It is normal for the fan to run if the AC is on, which it usually is.

"...but now it doesn't turn on anymore and car overheats ..."
So now you can drive the car (did all of the above problems just go away?), and the engine fan no longer functions so the engine overheats? How quickly? Sitting still? In traffic? At highway speed?

"... now the front end of the car is fully lowered when I start it the front does not raise ..."
How long did you let the engine run?

Punctuation would help a lot. A chronological description of the problems would help a lot. How many problems are there?

Get a good quality battery charger with auto-shutoff. One that has an AGM setting for charging.

Plug it in and charge that battery overnight.

Try again to start the car. Every symptom you've got is a dead battery symptom. You haven't said what you're trying to charge this with, but whatever it is, isn't working. You still have a dead battery.

I have Tried a good charger with atm setting.A d still won't hold the charge

Astro14

If it still won't hold a charge, then replace the battery with a new one.

Use an AGM of equivalent size/capacity as the original battery.

Charge it fully before starting the car.
