I have a 1999 Dodge intrepid 2.7l and have no power at the EBL or A\C buttons.Air only comes out on defrost and fan switch works.

Not silly, the sometimes put them in obscure places...here is a silly question, it does have a heater grid on the rear window, right? If so, look on the center console, or to the left of the steering wheel for the switch, that is usually where Chrysler hides them.

There is no inertia/ fuel reset switch on the 1999 dodge interpid. This system is computer controlled and comes with no manual reset.

sounds like the door is not opening that diverts the air

1999 oldsmobile bravada heat will not turn off is it hard to change adjustable thermostat and is that the problem?

well, try turning the knob from defrost to another setting.

Might be the same....You may want to do the diagnosis proceedure. Alot of times its the door actuators. Servos in replace of old cable design. Usually it will be a code 46. DOOR BLEND ACTUATOR SHORT TO BATTERY.
The DTC's can be checked with the MTC control and the Odometer Display of the Mechanical Instrument Cluster if a DRBIII® scan tool is not available. The MTC control can only be placed into the diagnostic mode while the engine is running and the vehicle is not moving. To place the system into it's diagnostic mode, adjust the MTC control to the following settings:

1. The engine must be running with vehicle not moving.
2. The fan speed set to any speed except OFF.
3. The temperature control knob in full cold (full counterclockwise position).
4. The mode control knob must be placed in Defrost position (full clockwise position).
5. The A/C button can be On or Off.
6. Press and hold the rear window defogger (EBL) button until the mechanical instrument cluster odometer display indicates an "AC00". The BCM will chime once and the MTC A/C button LED will begin blinking.
7. Release the EBL button and wait until the MTC A/C button LED stops blinking. This means that the error check and climate control door calibration is complete. NOTE: It is important that no other control knob or button is pushed until all DTC's are read. Pushing any button except the A/C button or turning a control knob will end the diagnostic test without showing the rest of the DTC's. There also may be other DTC's stored in the BCM not related to the climate control system. These DTC's can only be found using the DRBIII® scan tool.
   DTC's related to the MTC control head will appear on the odometer display in numerical form after the letters "AC". The odometer display will return to normal operation if no DTC's are found. If a problem is found, then the odometer will display the letters "A/C" followed by the DTC number. The odometer display can only show one DTC at a time. Under certain circumstances, more than one DTC could be in the memory. To scroll through any additional DTC's, press the A/C button on the MTC control. The BCM will beep each time the A/C button is pushed. Continue pushing the A/C button and recording the DTC's until the odometer returns to normal operation (note the letters AC will dissapear.
   

i have seen an ignition switch cause exact same problems you are having on 1 of these vehicles..needs to be replaced

your blower motor resistor is bad, it is a small electrical component located next to the blower motor under the dash, held it with two screws.

have seen ignition switch cause all of these symptoms..also make sure connections at switch are clean and secure..

check out selector switch,vacuum hoses ,check transfer door write if did not solve
