A few different questions here.
Shortly after I bought my Passat in March of last year, the bulb in the left brake light blew. Although I have the technical expertise of a crumbling brick, I worked out how to detach the light cluster and replace the bulb. A couple of months ago, I noticed that the same brake light was out again. Replaced it again. Yesterday, I saw that the stoplight in the same cluster was out. Before the car starts eating bulbs, I'm just wondering whether there might be a fuse/wiring problem for that particular light cluster, or does each bulb have its own fuse?
Secondly, yesterday after getting some fuel, I turned on the electrics (as usual) before re-starting the engine, and the display for the climate control started blinking on and off, with every part of the LCD display "lighting up", as it were - in other words, where the temp display might normally read "21", it blinked "88", but like I say this was happening with every part of the display, including all the symbols, arrows, etc. I tried turning the electrics off and on again, but it continued. With the electrics on, I pressed the button which reduces fan speed till the unit turned off, then turned it back on again, which got rid of the symptoms. Cool air continues to come out of the vents (although now I think of it, I did wonder on hot days over the summer whether it shouldn't get cooler quicker). Didn't happen again the four times I've started the car since then. I always run the climate control summer and winter, very rarely have it on the "ECON" setting, usually set at 18 or 19 degrees C in summer, 20 or 21 in winter, and I often vary the fan speed. No idea what yesterday's occurrence might be a symptom of, but if anyone else has experienced it before I'd like to know if it led to anything.
Thirdly, if I press the button (located on the driver's armrest) to lock all doors from the inside, the front passenger door immediately unlocks again. It can be manually locked from the inside by pressing down the button on that door, but it never stays locked by using the "master" button for all doors. At the start of the year, I did briefly experience a problem with the rear N/S passenger door refusing to unlock when pressing the button on the remote key, but this seemed to go away after happening intermittently three or four times. It's not a major worry if this is all that might happen (I rarely use this function), but I'm concerned that a problem with the central locking could lead to someone being trapped in the car, or the car becoming unlockable.
Finally, from time to time the one-shot operation for opening or closing the driver's window doesn't always work - the window only continues to open/close if I keep my finger on the button. This again is an intermittent niggle which doesn't particularly bother me right now, but again I'd hate to find that it suddenly just refused to close.
On their own, these aren't particularly troublesome, but all together, I'm starting to wonder whether there might be a wider ECU, fuse, or wiring issue to be concerned about. The car is five years old and has 114k miles up, if that's relevant. Any thoughts, suggestions or solutions will be gratefully received.
