Heater hookup on early CJ5

Glen, I checked and yes there is a third connection on the bottom side. I don't know how I missed that but it's there. Thanks.

 

Regarding your heater problem, I expect the TSM won't show you how to connect the blower motor wires and cables. Likely someone would have given you a scan by now, if it's in there.

How many wires are there, three? Have you determined the function of the switch with your multimeter? Typically this is a very simple circuit. I suspect there are no details out there because the circuit is simple and easy to characterize with a meter.

Cables will be similar. There is typically an air door that admits heated air, and a defroster door that directs air away from the floor and up to the windshield. A cable-operated water valve would be unusual for an old car. Usually the coolant goes through the core constantly, and the air doors determine whether you get heat or not. Sometimes a manual valve is fitted so that the core can be shut off in the summer. I would think this would have little effect in a CJ, since the cab is so drafty and leaky anyway - you would not be able to feel any air leakage around the heater doors.

 

Tim, sorry I'm not as experienced or knowledgable as you. I am familiar with mechanics and wiring. Sorry I didn't flip over the switch to see the 3rd spade. I knew and said there must be a power in somewhere. Glen was great and provided the answer and was thanked. All a nice helpful exchange, which is what the forum should be about. If you had followed the thread, remember I have no previous install to compare to. I am attempting to add the factory heater to a CJ5 that did not originally have it. I had already made assumptions about the cables and wiring, but I could only account for 2 of the 3 cables. I'm trying to identify the 3rd which to me only possibility was a water valve. But I don't know that for sure. Others also came to that conclusion. So I was trying to find a diagram that might show it. However the ones I did find also showed the newer controls that included vacuum. Once I was able to find the manual, it only showed the newer one too. Thus still trying to find the 'real' answer. This you don't need to be so condescending. If you have something to add, great add it to help other.

 

mickey does it have a flap over the heater core?

 

disregard i see you got it

 

No condesension intended. I hope you are not reading that into my reply - I understand that you were offended by my reply in your post about the service manual, and I apologize for being too hostile. The factory manuals are meant for the dealership mechanics. They assume a fairly high level of competence. So something that is straightforward for that audience would not be covered, except to provide service info.

I've been following and you guys have gone on quite a while about this elusive valve. Yes, Glenn has been very helpful. So far no one has been able to point to any part that fits your CJ-5. I think that you're probably on the right track with jeepermc's setup.

 

Exactly as pictured. I'll try to remember to look tonight but I have a hunch I will be working late the next couple nights.

 

It was just this part, "buy the frikkin' TSM? Jiminy H. Christmas. Not expensive .." that is, shall I say not exactly friendly. I have my own small business and understand people trying to get everything for free. That is not what I was doing. I know you did not know I have been on backorder for months, but jumping the gun was not very friendly. I agree that 2 months is bad and I am going to cancel the order if they cannot get it out next week and look else where. As for mechanical, I am very good at the concept. I was one of those with the cigarettes rolled up in my tee shirt with grease for ever under my fingernails back with my 69 Firebird and 68 GTO in the early 70's. Again I know you did not know that but I thought my original stuff was apparent that I had already thought about it and just looking for a more definitive answer, but maybe not.

But in the spirit of Christmas, lets start off on a new foot, i mean stocking.

 

This seems unequivocal to me. None of this "sorry that you took offense" mush. What more do you want?

Geez.

Thanks for trying to smooth this over, Glenn.

I'll forget it if you will, mickeykelley.

 

Ok. Back to the heater box assy.....

 

This is what is on my Dispatcher. This one is inline. Don't know what your set up looks like.

 

Bet you got an aftermarket in there, or some sole went to a junkyard and pulled one from something.
My '60 doesn't have any signs of a heater or hoses. It was an option and the original owner got it without.
Everything was a option except the drivers seat and the drivers side windshield wiper.

 

So I'm back to someone who has the original 3 cable system, where does the 3rd cable end up going? We need to find an original from the factory heater with that 3 cable control. Where are you.....

 

Ok. So 3 cables. One goes to defrost and that should be obvious. The air control goes to a flapper that is controlled on the top of the box portion in the interior of the jeep. After the blower motor. The temp control cable on mine goes to the flapper on top of the core in the engine compartment.

 

Those are the "inside the jeep" connections. The other one under the hood i didn't photograph.
