Replying to: knowitall1979 (Jun 24, 2009 12:11 pm) Nice mess you have there . Speaking generally the electrical stuff doesn't use much power and will tend to work (initialy) even if power is low, but starting takes a lot of juice and if that is drained trying to start (whether or not it turns over) it can lead to key getting stuck and various other symptoms due to low voltage. If the battery is original that may be a place to start as it could very well being showing its age even if it works most of the time (some places like autozone will test it for free). Next thing I would want to be sure of is cable connections both on battery side and perhaps to the underhood fuse box to make sure they are tight and not corroded. I had a little bump on the mating surface on the battery that caused a bad connection that lead to start failure once a month, very annoying till I fixed it. Also you would want to make sure the plastic part on cable end that is supposed to go over the connection on battery isn't tucked under and creating bad connection. If there truely is a rainy day thing where you have water intrusion in cabin causing problems you have to find the cause and correct that first and then see what happens.

Replying to: ray80 (Dec 20, 2007 12:32 pm) I currently have my aztek in pieces for the same problem. My battery connections are fine (even took the rubber piece off my neg. cable ), I replaced my battery and starter twice, I tested ALL my fuses they were good, but replaced some anyway. all my ground and positive connections are sound but my starter still won't engage(same problem as cathy's aztek)

Replying to: ryanhenderson (Jun 21, 2008 7:54 pm) you just described my aztek to the letter all I know is what it's not.... I have mine almost completely gutted trying to find the problem... I tested all fuses, they were good, changed a few anyway... I changed the starter and the battery twice... both battery connections are good.. all positive and negative connections on the van are sound.... People with the same problem have changed their p.c.m. and b.c.m. and that didn't help... I have my column pulled apart and there is a little mechanism that works in conjunction with the key cylinder via a plastic gear, I even pulled that boy apart there was nothing wrong with it.... I took a dremel tool and disassembled my key cylinder and there is nothing that would cause this problem.... I pulled out all my carpeting to see if there were any wet wiring, there was, and it's been drying for months yet I still have the same problemall wiring harnesses are clean and connected (even in the back of both fuse panels, which is no easy task). All of this started with my traction control going on the fritz then everything ryanhenderson described, now I,m at the point where I get all my accessories I just can't get my starter to engage.

Replying to: darc1 (Jul 20, 2009 12:35 pm) i can tell you exactly where the problems are with these aztecs,....theres 2 wire harness plugs that sit in the engine compartment just below the fuse box,...one fastened to the side of the abs mount and one fastened to the front,...follow the front harness toward the back of the engine,...about 8 inches from the plug you will find that the harness sits against or on the shifter cable for the transmission,..and the cable wheres threw the wire causing you the problems with both bcm,ecm,and starting issues,...repair it,..and move the harness away from the cable by fastening it up with tie wraps,...and your done,...let me know how u made out,...good luck Replies to this message: darc1 (Jul 20, 2009 3:06 pm) darc1 (Jul 20, 2009 4:53 pm) darc1 (Jul 20, 2009 4:53 pm)

Replying to: travis11 (Jul 20, 2009 1:44 pm) well, I checked out that shifter cable and wiring harness that you were talking about. Although there was wear on the shifter cable it seemed to be contacting bracket that the wiring harness attached to, and not the wiring harness itself. I still disconnected and closely inspected the harness and the wiring, but I couldn't find any damage (and I REALLY looked), there was only dirt. so I cleaned it then gave it a try...still won't engage the starter

Replying to: knowitall1979 (Jun 24, 2009 1:48 pm) I just had our 2001 aztec serviced by Maltbie Chevrolet in Lake George,N.Y. for all of the same issues you are having. At first they thought it was the IGNITION SWITCH so they replaced that. It still was not sending the signal from there to the ECM to start. So they followed the wires from the IGNITION SWITCH towards the ECM. At this point they explained in the bill after removing the protective cover off of the wires they noticed some corroding and while inspecting the wires some of them were corroded and a few were broken through. They used some G.M. splice kits to fix the connections and low and behold it started. So they re tried my Ignition switch aand mine was fine so they removed the new one to save me some money. The bill was $306.00 and it is running perfect now. It also fixed every electrical issue with the vehicle. (no start,security light, battery being drained) Most of the bill was for labor to find the problem so if you brought yours in somewhere with this message I am pretty certain this would fix your problem. And them knowing what to look for would save them time and you money.
