Re: Gtv Bonnet Light Is On When It Is Shut
Mine did this too after I had the engine steam cleaned. Think moisture annoyed the sensor, which resides in the passenger side recess that the bonnet pin inserts into. Looks virtually impossible to access and I just left it to see if it would heal itself with some kind words. It just gave up completely in the end, which doesn't bother me as when it thought it was open the whole time, the alarm kept screaming.
Try spraying WD40 in there and working the microswitch back and forth - might find some disturbed crud is interrupting normal operation.
