Question about 2005 Jeep Wrangler

2005 Jeep Wrangler Heater and Cigarette Lighters not working.

I have a 2005 Jeep Wrangler. There is heat blowing from the vents, but the heater fan won't turn on. It started out only working on high, so we ordered the resistor. By the time the resistor arrived, the fan wasn't working at all. We replaced the resistor, fan motor, the control panel, and fuses. Not the cigarette lighters won't work. One was working until yesterday. It's supposed to be below zero next week, and I drive 45 minutes to work. Help!!

May help - fuses supply power but also needed is earth return to battery. This is usually black wires running from device to the car metal. To diagnose you need a multimeter. Check body of cigar lighter is connected to the chasis with meter on ohms. (continuity test) good is zero ohms. If earth problem, check under dash to ensure all earth wires connect to metal chassis. Then with ignition on, check centre pin at back inside cigar lighter has 12 volts to side.
If not then check fuse has 12 volt to it, Now you can get to the fan, repeat all the tests on fan. Best wishes, its tedious work.

SOURCE: i have a 1999 Jeep Wrangler and the heater fan

If you bypass the resistor pack and connect the motor directly to the fused 12v supply then the fan should run at maximum speed. If so, it's the resistor pack that's blown: a very common fault on a huge number of makes and models.

SOURCE: 1999 Jeep wrangler, loose cigarette lighter

Hard to tell exactly from your short post, however, there may be a large retaining nut on the back of the lighter behind the dash panel. Or possible a large clip that retains it. I would check there first.

SOURCE: cigarette lighter doesn't work

before u pull panel, check for 12vdc with voltmeter inside lighter socket. If u have it, then clean contacts and/or replace lighter(not socket, wiring is fine) May save a lot of work. If you don't have voltage are you 100% sure you have right fuse and not the one below, above, or next to it? I still make mistakes with numbered fuses, which number is for which fuse. To make sure I start counting at 1.

SOURCE: 2000 jeep wrangler fuse keeps blowing?? What do I

That or the wiring to it is shorted at some point. Remove the connection at the center back of the socket and replace the fuse--if ok, replace or repair the socket. If still blows fuse, check the wire you removed for damage near any metal object.

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.

Heater only blowing out defrost vents


Open your hood and find a "T" connector right near the battery. Follow the line down below the battery (you will have to get under the Jeep). You will see that the line plugs into a 3 to 4 inch section of 3/16" tubing that is plugged onto a black in color, plastic box. Use a razor knife and trim off about 1/2" of this 3/16" tubing as it commonly cracks where it fits on the nipple of the black plastic box. The vacuum cannot build pressure properly with these cracks in this tubing, and therefore cause the selector door to malfunction when operating heat and a/c. It is a quick and easy five minute fix.
