location of fan switch, blower motor?

I posted a while ago about my control switches not working for my a/c... I changed the resistor and that was not the problem... i suffered thru the summer in texas without a/c... not easy to do... anyway, now that the weather is cooling down i can tolerate working on my 2005 Wrangler X again... i checked all the other posts have instructed me too, but would really benefit from seeing a picture of where these are located and what is involved with taking them out to have them checked or replaced... so, can anyone post a picture of where the fan switch and blower motor is located? any and all instructions would be appreciated... trying to avoid a trip to the repair shop, but that may be my only option... Thanks for any insight!

The HVAC blower can be accessed/replaced from the engine side of the firewall, at least so far as I know. I haven't done that particular job myself, yet, but I think it can be pretty easily removed/replaced after you remove the battery to gain access to it.

The switch location? Well, that's gonna be right behind the big knob that you have been turning to try to get the fan working.

Assuming the '05 is the same as earlier TJ,s, if you have no fan at all you need to look behind the controls and see if you have a melted connector back there. It could be the connector for the fan speed switch or the climate mode switch:

Pry up defrost vent cover running along inside winshield. Remove 2 screws. Remove ashtray ('05 may not have one in which case try to locate screw on the lower part of dash bezel. Dash bezel is big plastic thing that covers knobs, radio, etc.) Pull dash bezel straight off. From there you will see 2 screws holding the hvac unit (thing with 3 knobs) in place. remove the screws and look behind the unit for melted connectors. If the connectors look o.k you probably need a new fan switch, about 25 bucks. Good luck, let us know if you need more help. I'll try to post a pic of the back of the hvac controls.

I have inspected all connections and nothing is melted or even looks damaged what so ever... i would like to check the fan switch, but am not sure where it is located...

can anyone suggest a resource or book that will show the location of parts, pieces, etc... that way i will not have to ask where items are that may be located right in front of my face thanks guys for helping out!

The fan switch (fan speed control) is the thing that the fan speed knob attaches to. (The dash knob you turn to change fan speeds.) The connector you checked attaches to the back of it. It controls the fan speeds.

The best (by far) manual you can get is the factory service manual for the '05 TJ. Lots of diagrams and published by Chrysler for every year TJ. Check ebay, about 30 bucks.

Thanks guys! I will look to order the manual and now that I know the part I have been taking out and inspecting is actually the part in question, I will run that by the auto parts store to see if they can help me out...

Guess next question would be, do I try the fan switch or the blower motor first??? any idea what they should cost???

Much appreciated!

Most the time, it's not the fan, could be a melted harness connector on the switch, could be the relay, the only way to know for sure is to remove your battery and take the computer off the firewall so you can access the motor (three bolts) they're 5/16 if they're the same as the 99, as are the bolts holding the computer on the firewall. Pull the connector with the rubber surround, (might take some elbow grease).
When you get the motor out and the connector off use a bettery tender set to 12-volt, and touch the leads to the the motor contacts, (doesn't matter which to which, it will either run the motor forward or backward.) but if it doesn't spin the wheel, it's your motor. If it does, make sure the wires to your switch are reading right on a meter, there should be 12 volts and some change to all but one wire, that wire with no charge, is your ground, it should be green, maybe with a light green, it and another wire will be a little bigger than all the rest. Once you locate this wire, change your meter over to continuity, and check that green wire to a known ground, the bolts holding the fusebox to the body, behind the glovebox should suffice. If your meter rings out, your good, if not, you need to run a new ground for your switch, just use similar gauge wire, and run to the bolts hold that fusebox on (a crimping tool with some connectors will help) then splice into that green wire coming off the switch. That should solve your troubles. I just did this job about two days ago.
