Will not turn on when set to automatic. when switched to on position no hot air comes out of vent.

Reeeeeeeeeeally common problem on that vehicle is that the heater blend door gets stuck in position. It's a little hard to get to, and you will need to remove the glove compartment to reach it, but often the blend door gets stuck in the "heat" position and needs to be lubricated and coaxed to move.
Also, vacuum leaks will cause the heater blend door to fail to move. Most common culprit: The automatic brake release vacuum line has broken or fallen off. Do you hear a hissing sound from under the dash? FIND IT AND FIX IT :)

WHAT ABOUT ANY FUSE OR RELAY FOR THE A/C ?

They have changed thier manufacturing proccess, so it is not uncommon to see the styrofoam. As far as the light shining thru, you might want to chack and see if you have the vent setting in the open position. If it is in the open position, the square flap will be open, and depending on the model and design, you will be able to see light. The vents purpose is to let fresh air in the home, when the A/C is running, but it is not automatic, so the vent flap will stay open, till you close or turn off, the vent setting.
I hope this helps, please rate me, and contact me back with any questions.

The hot/cold switch is probably bad.you have a blend door box that opens to let the cold air in and closes to let the hot air in.From what you are saying this part is no responding to the switch movement.Make sure power is at the switch and power should go through the switch when put on cold air this moves the blend door.Some times the blend door goes bad and has to be replaced its under the dash on the right side.

Sounds like a bad heater control unit, or bad control module. You are bypassing the switch when you jump the relays, so usaully the switching mechanism is suspect.

the air distribution switch controls the air distribution and the fan, distribution switch in the 0 (straight down position) will be off. Car movement forces air into teh body, but with teh fan off there will be no air when the car stops. Does the fan run when the distribution switch is in any other position? it should respond to the speed settings of the fan switch.

There is a vacuum bottle accumulator that assists the distribution switch, sometimes this gets disconnected and the switch settings don't work.

Do you hear any noises if you turn the distribution knob while the car is running? suction noises, or flaps opening?

If not, then you likely have a vacuum problem (check for a white bottle in left front wheel housing, except convertible -> under the spare wheel, tank should have one or two vacuum lines connected to it (one for convertible). A disconnected or leaky line is the most likely cause.

Possible other causes are faulty air distribution switch; burned out fan motor; inoperative vacuum solenoid motors controlling air distribution flaps.

But check the vacuum accumulator first, if under the spare wheel, the lines are easily dislodged.

There is a switch located behind the lamp vent panel on the back of the set. Remove the vent panel and hold this switch in the down position while you turn the set on. The set should stay on as long as this switch is in the down position. If the set stays on, check the inside of the cover you just removed from the set. Locate where the switch rests against it and make sure that it is not broken. When you reinstall the vent cover, lay it flat against the back of the set and slide it down so it can catch the switch on the way down. Most times this switch will come loose and flip up while moving the set. Or if you just replaced a lamp and didn't get the switch back in the right position.

Start with the vent, make sure it's not kinked or squished behind the machine and that the outside vent is not clogged with lint. You should feel air blowing freely to the outside.
If the vent is ok, turn the timer to any on position without starting it. Wait 10-20 seconds and then check if there's heat inside the dryer.
If yes, the element has a short and therefore always stays on. Replace it.
If no, run the dryer for a few minutes and listen for the clicking of the relay which cycles the element.
If there is no clicking sound, check the hi limit thermostat & thermal cutoff for continuity and replace if necessary.
If those seem ok, it could be the motor (centrifugal switch inside) or the timer (shorted contact).
Good luck!

If not

The climate control was poorly designed on these cars.

There is only heat on the floor and defrost settings, due to the layout of the ductwork.
