JMARK Posted July 12, 2019 Share Posted July 12, 2019 (edited) I have a switch (looks after market) just under my hood release lever (see picture). I can't figure out what it is for. Does anyone have any ideas? It has 2 wires leading off to who knows where. Edited July 12, 2019 by JMARK extra info. Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted July 13, 2019 Share Posted July 13, 2019 That's a common aftermarket on/off switch that could be used to control anything. All you can do is to trace the wires from it and see where they lead. Do you see any non-standard equipment on your vehicle that the switch might control? For example, I've used very similar on/off switches to activate aftermarket rear fog lights. Quote Link to comment Share on other sites More sharing options...
Kriss2018 Posted July 16, 2019 Share Posted July 16, 2019 Help! I have 2018 used GX 460 Lexus with 16k that has an annoying vibration at idle. Vibration can be felt while idling in the driver seat. Doesn't matter if AC is on or off. Tachometer does not move stays steady. If I shift into gear can still feel. Car was bought at auction and sold to herb Chambers Hingham MA.

1990LS400 Posted July 16, 2019 Share Posted July 16, 2019 There are too many possibilities to speculate which is why you need a trained tech with appropriate equipment to diagnose. If I had to guess, the problem might be a defective spark plug coil. But a defective engine or transmission mount could cause a similar vibration. 1 Quote Link to comment Share on other sites More sharing options...
