Well I did a little more investigating last night. Borrowed a cooling system purge tool and a CO2 sniffer from one of the guys in my shop, the Purge tool is only a deep funnel with a radiator cap at the bottom so you can overfill the system and let it purge any air and keep full, I purged the heck out of the system and let it run, the funnel was almost empty as the temp started to come up, on the second cycle of the cooling fans the coolant level rose to the point of overflowing this big funnel and was bubbling and boiling like crazy!! Yet the temp gauge read normal
with it boiling away I put the CO2 snffer to work making sure not to suck up any coolant, only the steam vapor... no signs of exhaust, shut the car off and the engine cooled quickly enough to empty the funnel into the engine, still steaming like crazy, so I put the rubber tip of the sniffer right in the bottom of the funnel so I know all it was sniffing was coolant steam, still no exhaust... which makes me a happy camper in that I dont have to tear into the engine.
So, either that nice clean looking used radiator is plugged up, or the water pump isnt circulating. I'll run a garden hose through the radiator when I pull the front covers off to change the water pump.

When you change the water pump, change the timing belt. Change interval for timing belt and water pump is every 90.000 miles on that vehicle. You have to take out the fan assembly to change these item on those vehicles.
Good news about the exhaust gasses. One other thing you have to correctly orientate the thermostat. As in those vehicles if the thermostat is not rotated correctly it impedes water flow.

I agree on the timing belt at the same time. I feel confident the T-stat is in right, there was a little notch in the stat base the lined up with a corresponding locating pin (for lack of a better way to say it) in the stat housing. and I used just a dab of silicone to hold the stat in place while i put it back on the car.

Just a couple of other things. I forgot to tell you, you also have to remove the belt pulley to change the water pump and timing belt.
When you drain the water next time and refill, make sure the heater is full on, as otherwise you will never get free of air locks.

My 1994 LHS is having a new problem. My abs and air bag lights are steady on and my power windows are not working as well as my air/heat panel. no power to that display as well. I have done some other research and got an answer that it might be the ignition switch. the Person that told me this is an retired chrysler mech. he said that the blower motor pulls so many amps that it is not uncommon for the switch to go bad since it has alot of other things connected to it. he said that I might even notice some burning on the switch if i pull the cover off of it. I wanted to find out what you all thought of this? any other ideas as well. I dont have the money to go to the dealer right now and am really needing the heat to work right now incase i need to defrost windows and such since the cold weather is among us. please let me know if you have any more ideas. thanks

If an old Mechanic has seen this, it is a good place to start.
I have also seen reports that this problem can be caused by a grounding block behind the dash going bad.
Strange as it seems, this is a problem that could cost more than the car is worth to sort out and fix.
I would start with the ignition switch and see what you find.

the New ignition switch worked. It solved all the problems. The Airbag and abs lights went out, and the power windows worked as well as the heat and air. I am so glad since the cold weather is here. I can safely drive it again. If anyone has this same problem, I hope they see this post. Now all i have to do is some brakes and i think i should be good for now.

Were you ever able to find out what was wrong with this car, my 95 is doing the EXACT same thing you describe and I would love to know what it is before I spend thousands trying to figure it out! Thanks! Anybody else who knows feel free to chime in either. None of the gauges work in the dash and the transmission gets stuck at the same time (son't shift out of 1st or 2nd gear and engine revs very high). Seem to be related to eachother interestingly enough.

Sounds like your battery is dying or alternator is going bad...you might want to have your charging system checked
