I just downloaded the manual and looked at it. The BCM controls the "Accessory Delay Relay Control" circuit, which goes to the power windows and the power sunroof. The BCM is attached to the back of the junction box. So this setup is different than mine. It looks hard to get to. Do you have a...

The 03 goes straight from the ignition switch to the power window switch, no relay at all. So maybe the 06 relay is controlled be the BCM as you surmised. Mine actually had no power windows when I bought the car. I installed them and added the wiring according to the schematics I have. On the...

OK. I think that you are right - your Jeep is set up differently than the wiring diagram I have. My diagrams don't even show a window relay. What year is your Jeep? If it is not '03 than I think we might want to get a better wiring diagram.

bp87, Your low battery situation may have erased the programming of the key fob. How this works is the key fob has a serial number and the "key fob programming" simply stores the key fobs serial number in the car. If you google redo the programming, it might fix it. Google "program key fob...

Ksat, the 2003 manual I have shows no connection to the body control module. Steven

OK. So here is the end of the story .... I did the repairs above and am glad that I did. The antifreeze came out a dark greenish brown (wow, not good). I had put new antifreeze in when I put the engine in about a year ago, but did not flush it. The previous owner must have been using a different...

@gbennett21 What are the current symptoms? Give us some details and we will try to help you out.

Rigid - Thanks for the advice. I am going to do that also. Since I do have flow problems of some sort, I am going to replace the heater core and blend door actuator while "that deep into it". In addition, the thermostat and water pump are at the other end of the heater hoses, so I will take...

I have poor heat in my 03 Liberty. I have attached a page from the service manual with the diagnostic procedures. The coolant is correct and was changed early this year. One of the aluminum heater lines is much cooler than the other and it never really heats up. The blower and controls all...

Here are two pages from the manual. (BTW - You can find a link to download it on these forums). You can pull the resistor pack and test just about everything in the blower motor circuit from there. Check resistances (not just continuity) across each resistor and jumper: 1-2 (high), 1-3 (first...

Wow, if I had known this I would have tried this way. I talked to the service manager at the local Jeep dealer and was told that the computer would need to be programmed. On something like this, I would tend to trust you more (simply because you have done the task). Knowing this, I think the...

The use of fog lights and low beams together are explicitly allowed in Maryland law. Yes - DRL applications typically have a relay and a diode. The diode drops the voltage some and thus increases the life of the incandescent bulb. I do not know how DRL with LED headlights would be set up. In...

Yes, I could (and may) "go full original equipment", but that also requires a trip to the dealer to reprogram the ECU. Actually, when I was first getting the car back on the road, I found a new-in-box stalk in the backseat of a KJ at the local pick a part. It was the style with fog lights which...

LabRat - good point... I am in Maryland, and yes we have several requirements for foglights: 1) Proper aiming 2) Fog lights OR headlights on with wipers (I was previously unaware that fog lights can be used instead). 3) Height min and max. 3) No fog lights with high beams. 4) ... (lots more...

I am thinking of adding factory fog lights to my 2003 KJ. I would use factory lights, and (possibly) install a separate switch. I know how to do wiring. The Jeep does not have DRL. I can easily hook up the fog lights to come on automatically when the low beams are on, or when the running...

Oops - I just noticed that I posted this in the KK General Discussion, It should be in the KJ forum. Sorry. I tried lock to lock many more than 25 times. I am using power steering fluid. From the Jeep manual "CAUTION: Use MOPAR Power Steering Fluid or equivalent. Do not use automatic...

I have an 03 KJ 3.7 project I just replaced the engine and a leaky power steering pressure side hose. The pump and hose were disconnected and sitting in the garage for a couple of months while I messed with the engine. When I put everything back together, I tried to burp the power steering and...

Update: I finally got back to my project Jeep last week. I got a replacement engine from the local junk yard and it is in and running. Lift points in the back are easy. Just remove the studs used for the "Y" ground strap at the back of each head. It has a small diameter stud for the ground...

BillWill - Good point about the tone rings. I should have mentioned that I have done some basic research including getting the factory service manual and reading TwoBobsKJ's engine swap thread (lots of good jnfo there). I have also read conflicting reports of which model/year has which...

I am replacing the engine on my 2003 Liberty. It is the 3.7. I started on it today and got the wiring and the intake off of the engine. I have a couple of questions. 1) Lifting: What is a good point to attach a chain in the back of the engine? In the front, there are mounting holes for the...
