So, when I turn the key to the On position, there is a rapid clicking noise coming from the glove compartment area. It also happens when I turn the vehicle off (key still in the on position). It isn't the starter, as the blazer starts fine. When the motor first begins to run the clicking continues for about a minute. I was wondering what this could be and how I would be able to fix it. It is more of a nuisance than anything.

Thanks for all the advice and help.

Mog...there is the turn signal relay in that location....also that sounds like some of the symtoms of a turn signal switch starting to fail
Just going from past experiences with mine..
Search turn signal problems..there is a ton of info on this and D.I.Y. pics on replacment if it is your problem
