Where is the TDM located
The tdm ( theft deturent module ) for the car is above the hvac case behind the glove box . Lower the glove box and release the catches on the glove box to let it fall all the way down and the module is way up above the hvac case. The easiest way to by pass the vats system as long as the module is good is to measure the resistance of the pellets on the key and go to radio shack and get resistors that add up to the resistance of the key and wire them into the wires at the bottom of the steering column.This will trick the system that you are using the proper key .

I have a 93 lesabre. The air and heat controller
Hey Cap'n, all the heat and A/C is actuated by the controls and these controls are ALL vacuum actuated. Make sure you have vacuum to the controls from the engine. There's a 4 inch round ball under the hood on the pass side near firewall. This ball is the vacuum reservoir, must have vacuum to and from then thru the firewall to said controls. If there's vacuum everywhere, it HAS to work properly. Check all vacuum lines for leaks, cracks, connections, all the above.
