Hi, thanks a lot for your guiding. I am actually done wiring and I have come across some problems I will type them below, can you please look with your husbands if you he had the same issue.
1st problem and most important one: My window switch for passenger side isn't working at all, when I was done wiring it twitched the window a little bit then stopped, I checked all the fuses etc. they are fine.
2nd problem: Sometimes the driver side window switch doesn't function properly in other words, when I take down the window it works, but sometimes taking the window up doesn't work and when the car door is open on driver side it doesn't work either.
3rd problem and a minor one: When the side mirrors are folded after locking the door, when i unlock the car and then open the door and shut it, it unfolds the mirrors.
4th problem: I didn't really understood the output and input close/open mirror wires and does the mirror fold switch needs to be pressed or not?
Ps. Also if I lock my doors while the car is on with the lock switch button on driver side, it folds the mirrors...
My husband just advised me that, as the fuses are OK, and assuming the unit is not faulty and that the wiring is the same on your LHD car (as on my RHD car), these problems are most likely caused by incorrect connections when the TomTop unit was wired to the car's loom, or loose connections, or a combination of both.
He suggests you have a very good look at Post 83, particularly the wiring diagram (which is the correct advice, as it worked for him) and then meticulously go back over everything you have done step by step, testing each function and connection with a test light to hopefully find the incorrect (or maybe even loose) connection or connections. Study the colours very carefully as some of the wires in the car's loom are very similar, as he mentioned in Post 114. Again, he suggests you read his Post 114 about some of the interesting issues he encountered, especially about some choices you have to make with the wiring colours, in particular making sure that you only make the connection to the car's Pink Wire right behind the actual door lock (you will need to add a piece of wire to extend the TomTop wire to reach it).
Also, even if all the wiring has been rectified, you may still find the windows are out of sync, which is a common issue. This is usually remedied by the following:
1. Turn ignition on
2. Open both doors
3. Close both doors
4. Turn ignition of, then on again.
He wasn't too sure about your minor issue with the mirror control button, which again may be affected by a faulty connection. Since he installed the TomTop unit I have never touched that button again as the mirrors just simply close when i lock either door and open when I hit the start button, as intended.
Hopefully this may help you further, otherwise my husband suggests a visit to an auto electrician may be your only alternative (rather than risk costly damage to the electrical system).
Once more .. Good Luck from both of us.
