I have a 2004 Dodge Intrepid ES and my climate control works sometimes and sometimes not. The temperature display comes on and off. It doesn't matter where I put the blower whether its to the floor the top vent or the face vents once the temp display goes away so does the the heater and the A/C. It will continue to blow out the vents just not any hot air when the heater is on or cold air when the air conditioner is on. Is it an electrical issue?

SOURCE: dash vents not working

I hate to question your intelligence, but are the vents open with the knob below them?

SOURCE: Air conditioner works but not blowing out the vents

Check the air directing servo motors under the glove box. they are 2 black boxes about 3"x3". you have to clean the contacts of grease with contact cleaner spray or alcohol.

SOURCE: passenger side blows hot air when front control set to Air

you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.

SOURCE: climate control system only blow air out defrost vent

there is a good chance that you blend air door is stuck closed over your heater core and therefore not allowing the heat to flow, also your door that opens and close your direction of flow from the floor ,das,vent and defrost.your going to have to remove the lower cowling of the dash on the passenger side analso some of the center dash to actually check to see if the cable,servo motors. are acuating the doors.the issue could be just a stuck door or a misaligned cable or that it came off. that falls under the mechanical side of probabilities. electrical would most likely be a faulty selector switch or a servo motor

it will be hard to diagnose with out having my hands on it but try this.

this vehicle is known for blower motor resistor failure.

under the dash on the passenger side next to the blower motor there is a resistor attatched to the blower motor case it will have a single plug with 5 or 6 wires in it, they are normally within a couple of inches of the blower motor, remove this resistor and look at closely for any signs of burning this is a common problem, you can buy one at any parts house, do not operate the motor with the resistor removed from its mounting hole or you will damage it.

if the resistor looks good than purchase you a test light and drop me a line and i will explain how to test the entire system its not hard to do.
