Perry,

That is correct. The idle control module is located behind the glove box. You will need to remove the glove box liner. If you look closely there are small round 'pins' holding the interior liner of the glove box that slide out from the surround and pull out. Most of them will come completely out which is not an issue. Look closely as I believe the fuel pump module is there as well. You will want to confirm part number before pulling. Once out you can carefully 'pry open' the module and closely inspect for 'breaks' in the solder. Some folks have been able to re-flow the solder and fix the module. I ended up sending it for an 'exchange' for a rebuild from Programa at a cost around $200.00. I would also suggext that you also pull the Over voltage Protection Module. If in the same location as mine, you will find it behind the fuse box on the outside kick panel of the passenger side. It takes 2 or 3 very small screwss to remove the kick panel to access the OVP. Pull the OVP and check the fuse that is inside. The OVP is cheap compared to the ICM.
