Your heater may be blowing cold air due to issues such as a malfunctioning thermostat, a clogged air filter, low levels of refrigerant, or a problem with the heating element. It is recommended to check these components and consult a professional if needed to resolve the issue.

Your electric heater may be blowing cold air due to issues such as a malfunctioning thermostat, a clogged air filter, or a problem with the heating element. It is recommended to check these components and seek professional help if needed to resolve the issue.

Your car's heater may be blowing cold air instead of heat due to issues such as low coolant levels, a malfunctioning thermostat, a clogged heater core, or a faulty blend door. It is recommended to have a professional mechanic inspect and diagnose the problem to determine the exact cause and necessary repairs.

To fix the heat in a 94 Chevy S-10, you can start by checking the coolant level in the radiator, ensuring the heater core is not clogged, and confirming that the thermostat is working properly. If these checks don't solve the issue, you may need to inspect the heater control valve or the blend door actuator for any malfunctions.

In cold weather, the temperature gauge may fluctuate as the thermostat regulates the temperature by turning the heat on and off to maintain the desired level of warmth in the house. This cycling on and off is a normal part of the heating system's operation to keep the indoor temperature consistent.

It sounds like there may be an issue with the wiring or controls of your temperature switches. Check to see if the wiring is connected properly and if the controls are functioning correctly. If the issue persists, it may be best to consult a professional HVAC technician for further troubleshooting and repairs.

This type of reversal in a switch can happen due to a wiring issue or a malfunction in the switch mechanism itself. It is important to have a qualified electrician inspect and repair the switch to ensure it is functioning safely and correctly.

It is possible that there is an issue with the blend door actuator or the heater control valve. These components control the temperature distribution between the front and rear heating systems. I recommend checking these components to see if they are functioning properly.

The heater resistor is quite simple to change. Unplug the wiring harness from the heater resistor. Remove the heater resistor retaining screws. Reverse the process to install your new heater resistor.

It could be any of a number of reasons. Such as: You are out of freon. Your compressor doesn't work. Really the only thing your light being on is telling you is that the fuse isn't blown. And your heater has nothing but the blower motor and duct work in common with the air conditioner. I would suggest a good mechanic or a Haynes or Chiltons Manual if you are mechanically enclined. Good luck. Jeeps are notorious for the AC going out more than likely your heater core box is full of debris and the fore you have to go to the dealer ship and they cahrge you $850 to clean it then they tell you how you need a new condenser and that is another $850 this has happend 2X to me my suggestion is get rid of it additional info: there are a number of posts on Wiki concerning AC problems with Jeep GC's. My experience is that you probably are having a problem with a clogged drain tube leaving the evaporator box. This is assuming that your freon system is fully charged. I would have a reputable AC tech check the freon first and then turn my attention to the drain. The previous answer is correct about the debris in the evaporator box and it is a result of extremely poor engineering on the part of Jeep. Keep looking on line and you will find out more.

Of course, you have to be sure that the compressor is working, the system is charged and things are getting cold. A simple check of the refrigerant lines going into the firewall with your hand will give you an indication of whether the system is cooling or not. If the lines are cold, your problem may be with the blend door or re-circ door. The blend door diverts some or all of the air flow through the heater core. When this door breaks, you lose control over the air flow and can see problems with both heat and AC. Usually the broken blend doors fall to the bottom of the heater box on the GC and block heat. However, it is not uncommon for the doors to fall crooked and kill the AC function also. The re-circ door is also susceptible to failure. This door chooses between external and internal air going into the system. When it fails, you are contstantly pulling hot, outside air into the system, greatly reducing AC efficiency. Both of these fail modes are common. Check the HeaterTreater listings on Ebay for more diagnostic information and an inexpensive fix for the problem

under the dash pass. side look at heater you will see a plug with several wires that look like thy go into the heater there is a one screw plastic cover over this area so your feet dont hit it remove then uplug the wires then take the 2 screws out of oval shaped sensor and pull it out of heater you will see some transister on the back side and a little coil . replacing this will cure it usually . but first remove your heater blower and make sure it turns freely and not seizing.

You have to take off the glove compartment, and some other paneling to get to a little motor with a whole bunch of gears right behind your center console. Just put grease (or Vaseline) on all of those gears, and you should be good to go!
