Chrysler Repair: 95 Concorde heater: no functional control, 1995 chrysler concorde, chrysler concorde

Question
Good evening!  My parents have a 1995 Chrysler Concorde in excellent condition.  They purchased it almost a year ago for my brother who has sinced moved and left the car behind.  They have been driving the vehicle for months and the heat will not shut off!  They've tried every button, they've even tried to change settings as to where the heat comes out and nothing is working.  It was very uncomfortable for them to drive the vehicle in the summer as it was heat the whole time, the ac wouldn't even turn on.  Is there a way to fix this?  Do you have any suggestions about anything?  Please help!

Answer
Hi Nicole,
I hope that heat problem is solved.  If you would like to tell me there is a "Thank/rate the expert" button below which if you click will take you to page where you can "comment".
May I also ask a favor? On that same page you will see the question "Would you like to nominate this expert to be 'volunteer of the month"? If you will click on "Yes" that would be appreciated.  I am competing for that recognition which is based on nominations from questioners like yourself. Achieving it will increase awareness of the Chrysler repair category.

Hi Nicole,
I would start with the fuses (and fuse-like devices). There are two of them involved in powering the heater/ac system. First, take the end cap off the driver's side of the instrument panel and look at fuse #6 in that fuse box to see if it is blown or has a subtly cracked wire inside. Second go to the battery where you will find 4 wires associated with the + post clamp, the thinnest being brown in color. That wire is actually a 'fuse' which can burn through and 'open' so try pulling on it from its ends to see if it separates. It goes to a black 4-wire connector on the left side frame rail in the engine compartment. At that point test for whether there is or isn't 12 volts on that wire by means of a 12v glow light or a voltmeter unless of course you find that the wire disintegrates when . If you satisfy yourself that voltage can get through both of those devices and reach the heater/ac control panel thereby then we would need to do some self-testing of the system. But I need to know if the control panel is conventional or digital (temperature settings shown on a panel or not) so as to describe how to do the self tests.
