We own 2 different 2005 Jeep Grand Cherokee Laredos. Sometime when either of us try and start our cars it will not turn over. Apparently, we need to “jiggle” the gera shit and then it will start. Sometimes it takes several jiggles brfore the engine will turn over
There is a switch there to make sure you are in park or neutral before it will allow you to start it. It is a good idea. Likely it needs to be replaced, cleaned or adjusted.
