I have a Passat B5 1999 GLS and it also has the knob icon indicating power folding mirror potential. The person I bought the car from told me that it does have the power mirror folding. He never said it didnt work or that he had never used it. When I bought the car 2 weeks ago, it was not working but I assumed it had worked in the past. Based on what I have read in the forums here, can I assume that the feature doesnt work because I have a GLS and not a GLX model? What are the other differences between the tow models? Does anyone have a GLS model that does have (stock) power folding mirrors? If this feature is faulty in my car, how can I trouble shoot? Thanks so much.
