Chrysler Repair: 2001 chrysler voyager 4cyl. a/c and atarting problems, chrysler voyager, battery clamps

Question
Roland,
I found some information from past questions on this subject matter , but this is my delima. MY 2001 Voyager's a/c blower was only working on the high setting. Yesterday, I disconnected the switch to the a/c blower and got power going to the resistor on the blower motor. I did not have anything to test resistor and I couldn't find the part so I put everything back together the same as I found it. I drove home from work 20 miles with no problems. @ 2 hours later, I went to use my van and it wouldn't start. It was trying and would start for a second then kills. I went off for an hour, came home, and tried again. When I placed the key in the ignition, codes p1684 and p0456 apeared, but there could have had more. After the van did it's code thing, I was able to start. I did this a few times with no problem. Then it wouldn't start again. Waited a minute, it starts. Any idea on what might be the problem?
Thanks,
Steve

Answer
Hi Steve,
The resistor block as shown in the '98 manual is in the back of the engine compartment, mounted on the wall itself under the wiper module. It has a 5-sided plug. It is reached thru a hole above it by reaching thru the hole. there are a couple of spring clips on the sides that you depress in order to release it into the cavity for removal. One of the resistors is burned out so that is why you only have high speed.
The 1684 means the battery supply was disconnected recently but if that is not true check your battery clamps. The 0456 means there is a very small leak in the gas vapor collection system (check the gas cap and the hoses of that system as shown on the underhood sticker). The no start (rather than a no starter) smells to me of a security system that is unknowingly alarmed due to a loose door latch or other issue with the wiring from the door locks to the body controller. You can work around this if that were the case by never using the power door locks or the door key to secure the van, but rather just use the manual push buttons to lock up. That will prevent the system from arming and thus not false alarming. Try lock/unlock either front door with the key when/if it happens again to see if that clears the system and allow the engine to run as normal.
