Ok, if you are trying to use your AC and its not turning on, odds are your refrigerant levels are low, the system will not turn on when low fluid levels are present so the system doesnt burn up the compressor.

If your blower motor is not operating, you may have a fuse blown that needs to be replaced, or the control chip that plugs into the blower motor (for fan speed settings) has burned up (easy fix).

If your climate control is not throwing out heat when you change the settings to hot, you have a leaky vaccume line and the vaccume pressure is not strong enough to open or close (depending on setting) your blender box. Although typically when a vaccume line springs a leak you will have issues with your selector switch as well (defrost, vent, floor)

Also pay attention to your temp gauge to make sure the thermostat is operating properly, and the engine is not over heating ro getting excessivly hot! If it is, then you need to replace the thermostat ($8 part)
and go from there. Also you should check your heater core, if it gets clogged or has restricted coolant flow, your system wont have the heat it normally did (if any) when it worked properly.

This is just a quick summery of the area's you should be looking into for the problems you are having! thanks for using Fixya.com and good luck, I hope I have helped make resolving your problem alittle easier

Heat not working on 99 Jeep Wrangler. Blows cold air in vent and defrost.


You may want to check the two water houses that feed the heater core. they both have to be hot. (they are usually located next to the thermostat housing.) If they are cold first check the coolant level. Fill up if needed, then you may have to check of there is an obstruction by the housing or the heater core is clogged up. I would first disconnect the hoses and see inside the thermostat housing with a lamp. Also blow some Air inside the heater core to see if flushing is needed. Well if those hoses are both hot then that must be a problem inside the cabin with the vents selection. Either an electric switch or cable. But there are already a few things to check first.

2005 jeep wrangler blows warm air not cold


Well this is different since most questions now are about no heat.
If one ac line is cold and the other is warm, I would suspect a blend door under the dash is not working. The blend doors direct air thru the heater core and the vents.

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.
