Engine dies & other electrical problems

I'm thinking of buying an 02 Limited from a buddy. It's got the straight 6 and it runs and drives good. But he said that they are selling it because the engine will just die sometimes, but it only happens when it's really cold outside.

He said it also has a lot of other small electrical issues, one of the heated seats doesn't work. The power seat memory doesn't work 1/2 of the time but sometimes it does. And he said it's throwing a few codes. I haven't gone to look at it yet, but wanted to see if you guys might know anything about the issue with the engine cutting off when it's cold outside.

What am I getting myself into here?

A huge pain in the *** and waste of time. That's just my opinion though, as someone who has had (and still has) electrical issues with his WJ. I haven't had a speedometer in almost 6 months now, among a myriad of other issues like no power windows or auto lights, etc.

There are other WJ's out there. Unless this thing is exceptionally cheap, I wouldn't go for it. There's a reason he is getting rid of it.

If you don't have time to do it right the first time, how do you have time to do it over.

I was hoping it might just be a cam or crankshaft position sensor. Any ideas?

Looks like I'll be able to pick this up in the $3000 range. My wife is set on a dark colored Limited. It's got to be the V8, heated seats, sunroof, leather, etc... There is only 1 for sale in town at a good price and it has body damage and rust so we passed. The rest are all over $7,000. There are plenty of Laredo's and 6 cyl's out there between $4000 and $6000 but that's just not what she's been looking for. This one is, but has issues.

So what's the deal with these? Every once in a while you'll just find one with crazy electrical gremlins but some of them are just OK?

Sounds to me like it might just be a bad CPS or an ECU that needs replaced and a little bit of soldering in the heated seats. But again, that's why I asked on here first. What makes you guys think these are not an easy fix? Known problems?

And I see that you are parting out your 04 due to electrical gremlins. What were you having trouble with?

3k?! I paid 3500 for mine that was in 100% working order at the time.

Way overpriced for something that isn't in great working order.

My troubles were that all my dash gauges would go haywire, SKIM would come on and shut down the engine, or it would still rum sometimes with the SKIM on. Could not trust it to drive it. It had 317.XXX miles on it and a lot of under carriage rust and I figured I did not want to put the money into it to get it fixed. It also had the major dash wire harness connector all corroded out. New harness was over $1200.
It is now history.

Your looking at a limited with the 4.7 and dual zone A/C. 4.7's I believe are noted for head problems and the dual zone is noted for blend door problems, just to start.

In your original post you said a straight 6 and in your second post a V8, which is it?

I think it is one thing if the turn signal gets a little funny when its cold but this could be a world of problems. I had similar stuff happen to a vehicle and it was after it had flood damage in it because im in a hurricane zone. Would have had to rewire just about everything inside of it (it was a little car and a lot of water). You never know what is going on but if temperature is a factor you can start by making sure everything has a solid connection.

If it was me i would jump on it but I'm also almost a master tech ( just two more test to go) and about 10 years of auto exp under my belt. dealing with electrical issues is pretty easy if you have the time and proper tools and knowledge of testing. Also be it known that finding a wiring harness for these vechs is about as fun as running face first into a wall lol. Do you have a multimeter?

The head problem is from people letting it over heat therefore warping the heads. I'd rather deal with that then the famous cracked head the 4.0s have
Not all limiteds and overlands have blend door problems and honestly, they are easy to fix. Mine is at about 150k and still on the stock blend doors.

It's the 4.7. I thought it was the 6 but later found out it was the 8. I still haven't even looked at it. We're going to go see it tonight.

Yep, I've got a miltimeter. I also don't mind doing a little bit of work. But I really don't want to be doing a little bit of work ALL THE TIME. I'll check it out tonight and get a list of what all isn't working.

This one does have the blend door problem. At least I think that's what it is. He said it is stuck on cold air. The AC works but not the heater. He replaced the heater core and it didn't fix the problem.

Yes that would be the blend door or the actuator that controls it, but most likely the blend door
