Hi all. Is this the unit that controls the electric windows (front only, rear are manual) and the sunroof? Window operation became sluggish then packed up all together. Nether windows or sunroof will respond to switches. All fuse' OK. Battery was dead the other morning and a quick drain check showed 00.12A so I disconnected everything I could but 00.12A still showed on meter. Then I remove this unit and now I have 00.00A. Does this unit control anything else? Do I need to buy the exact unit as per 61.35.8 369 483 etc?

Really appreciate thr help.
