Question about Jeep Wrangler

1 Answer

Air won't blow hot or cold, at any speed.

98 Jeep Wrangler. The air conditioner won't blow any air at all. Hot or cold alike. I can hear the compressor kick on when I turn it on but no air movement. I have already replaced the fuses, relays, and the resistors. I want to check the blower motor to see if it is recieving power but I can't seem to find the power source. What else can I check to troubleshoot this problem?

On my grand, there is a variable resistor that controls fan speed. The wires feeding the resistor melted down. Turns out it was a very common problem for the year I have. I would look there first and eliminate that possibility. The power should be frigging fat wire about 8 or 10 gauge and is fed from one of your electrical junctions under the hood. The fusible links can look ok and actually be faulty, so test for the voltage and/or resistance at these points. If It is still down, and you are able to remove the fan, do a simple check to make sure its able to spin freely.

Heater runs but does not heat


If it is blowing air at different speeds inside the car, I think you are saying the blower works fine, but blows no heat.
If it is running different speeds but is not blowing inside the car, you probably have a plastic flap inside the heater assembly inside the car that is not opening, not allowing the air to come in.
That might likely be a vacuum issue, or maybe a mechanical one. (whatever is supposed to open the flap)

If the flap is working and you are getting different amounts of air inside the car according to the speed of the blower fan setting you have selected, go to the engine temperature.
Is the radiator getting hot?
Have you a temperature gauge to tell if the engine is hot?
If not, you will need to warm up the engine, and then determine if there is hot water in the radiator.
If you pull off the cap to see, it could blow up on your face, so you will need to find someone who can help you with this.
If the radiator is hot after about 10-15 minutes of the motor running, you are perhaps not getting hot water to the heater.
You would need to check the temperature control to see if it is working. This is often a mechanical switch located near the firewall of the Jeep under the hood. Usually it is the size of a small fist, and has a heater hose running into and out of it, and has a wire attached to the top.
It might have a wire to it that should move when you select hot or cold inside the jeep at the control panel. Sometimes the control wire will rust or break.. The heater hoses should be hot if the hot water is running through them.
If your radiator is low on coolant, often the heater inside the car will not work.

1998 Jeep Wrangler not blowing hot air. Fan is blowing cold air. Suggestions?


your heater hose or heater core could be plug, or your flap that opens inside of the heater housing may not be opening like it should. It operates off a vacum line, check all your vacum lines going into your heater housing.
good luck

96 Jeep Grand Cherokee will not blow out hot air


It's possible you are not getting enough coolant flow to your heater core. Try pulling the hoses off the core, blowing it out with air compressor, fill with water and blow out again. Try this about five times and see what happens. Alot of times these cores will plug up or have restricted flow. They will blow warm at low speed but it won't flow enough hot coolant through to stay hot on high blower speed.

1992 Jeep Wrangler heater not blowing hot air


How often has the coolant been changed? My only guess is that it hasn't and the hoses and the heater core are plugged up with goo and a flush is needed

Jeep Wrangler 03 A/C stopped working abruptly


This may be the AC compressor cycling switch is defective. It is located in the larger of the 2 AC lines coming from the compressor, it has a wire connector to it with 2-3 wires. To verify this is the issue jumper the connector with a small piece of wire and see if the compressor runs.

Try this disconnect the heater hoses from the heater core use a hose to backflush the core. Then reconnect and try again.
