2000 s430 battery was drained flat, after recharge battery, everythings work fine except sun roof won't operate, does it require reprogram ? how ?

Did you use a voltmeter an check for B+ voltage to the switch ?

• The roof opening panel does not open or close

• Roof opening panel adjustment.
• Battery junction box (BJB) Circuit Breaker 601 (30A).
• Circuitry.
• Roof opening panel switch.
• Roof opening panel motor assembly.
• Roof opening panel lifter assemblies.

• Go To Pinpoint Test E .

do you have a sun roof and if you do the drain tube in block with debits ,the tube is located on the sun roof channel .

Hi.
I was having trouble with my sun roof on a 2004 Montecarlo. I had two issues water coming in and would not operate fully. I could toggle the switch and it would not move very far. this is what I found. I started to pull down the lining and saw that the motor was in front of the sun roof.
I found the drain lines on the front side corners of the tray around the inside of the sun roof. I found that the tube ran down the pillar's and out between the door hinge's. I took them off and blow them out one was plugged up. That fixed the water problem. The roof would move with help from me pushing. I got it opened and noticed the grease was hard. I cleaned up the grease and removed most of it with WD40.
Now the sun roof works good as new.
I thought the water problem was because the roof was not fully closed but I guess it is designed to have water pass by the roof seal and have it drain away. I always noticed water under the car after a rain or a car wash but did not realize iit was the sun roof draining.

Trouble shooting required:
What voltage is do you get with a multi meter at the battery terminals when the vehicle is running. (looking to see the alternator is putting out the required voltage)

What voltage when it is not running & during cranking. (testing the quality of the battery)

Does the battery go flat overnight? What if you disconnect the battery overnight? (Looking to see if something is draining the battery when the vehicle is not running)

you have to stick the key in the trunk and turn it to the lefy while hittin the unlock button on the key pad 35 times has to be 35 and it will unlock. my battery died and it locked the trunk as u know i coudn't jump it cause the battary is in the trunk haha but yeah 35 times while hitting the key. mercedes wont tell u but my buddy works for inskip and filled me in your o so welcome from one s430 owner to another

As is typical with all German cars this tops operation requires a scanner to analyze, off to the dealer with you.

I had the same exact problem with my wife's 2003 eclipse. Her sun roof, center display, key fobs/ alarm, radio

you must have a fuse that went maybe a main fuse if you have car manual it will tell you were fuse is..

check fuse F1.401, 30 amp in central junction box (in truck). Check your owner manual for fuse information.
Headliner must be removed to access motor.

well the easy way to check is open the sun roof look from the top of the car inside the sunroof is there sitting water in the little drain areas around the sunroof if so the drain is not working... if no sitting water pour some water in see if it drains if it does drain it is prolly the seal isself so if the water drains fine then close the sun roof and spray it with a hose if it still leaks in prolly the seal...if its the drain hose you will have to trace it it useally runs down the a piller let me no what you find or have other questions
