Anyone?
Its the wire shown with the silver sleeve and the grey connector in the center of the pic. It comes out from behind the coolant res.

I could be wrong but that may be the vacuum lines mentioned in topan's post a bit down the chain at viewtopic.php?f=5&t=61240

NEVER MIND, my bad. Should have read the post all the way to the "gray connector". Senior moment.

that looks like the coolant level warning light switch. stick your hand under the coolant tank and feel if it is connected.

Yes, that is the coolant low level connector.

When it is disconnected it should turn on the code light, do you see the code light on the dash?

Low coolant level sensor, plugs in on the bottom of the reservoir.

I finally got around to this. It was in fact the coolant sensor. This sensor must be like a float switch. The problem is, when its disconnected, it doesn't trigger the dash light. So if the sensor goes bad, you wouldn't know unless you physically saw that your coolant was low. I knew my coolant was not at the upper line, but i didn't know it was low enough to trip the sensor. When i plugged t in, the dash light came on. Another poor Chrysler design i my eyes.

Hm, I know it's fun to pick on Chrysler and I've certainly done my share but if a "fluid level" plug is disconnected there is no power to send a signal although I suppose in theory it's possible to design a check circuit to confirm that the plug is attached and getting a signal but I'm not sure anyone does that. Not to mention that if it's a float level switch so is the one that drives the gas gauge-my point being that if that gas level switch goes "bad" the only way you will know is when you run out of gas unless you notice the distance traveled.

Real bottom line is relying on a nanny switch with light to warn you that fluids are low is not and never has been a good idea. Sorry but they are called idiot lights for a reason. Don't jump on me I rely on the idiot lights more than I should just like most of us.
