Heat control

[ecohen2]

My heat see seems to be on all of the time. The control on the center console is connected to a cable which moves properly but no matter what I do I am getting hot air from the vents. My guess is that the cable is broken at the valve.

Where is the heater valve and how do I reach it?

Thanks,
Ed

This is one of the aggravating things about the Scorpion. The water control is actually vacuum operated and is inside the center console. Even if it's working correctly you'll still get hot water all the way up into the center console area. If your vacuum lines are bad it won't operate. Mine were chewed up by mice pretty badly.

I plan to relocate my valve back into the engine compartment with a three-way that will bypass the line to the console when off. Still need to get the specifics from Allen Lofland who has done this.

Ok, I am really confused. The manual gives directions on "Removing and refitting the heater cock" It makes it sound like there is some valve somewhere below the console that is controlling the flow of coolant. It even describes how to drain it, but it doesn't say where its located.

Remember, I don't have the push buttons on my panel, I have 3 sliders with cables and a fan slider that does the power. So from what I can tell, I have no vacuum lines going up front because all of the sliders work without the engine running.

If you don't have the push buttons, then I have no idea how it works. Perhaps one of our British or European friends can help. Many of their cars didn't have AC whereas most of our in the US did have AC.

Ed,

The control valve is in back of the center console (way back) almost to the front firewall. There are two small diameter metal water tubes that run from the rear bulkhead (where they connect to the rubber heater hoses) to the front of the car. They run under the central tunnel in the passenger compartment and exit through a rectangular opening directly under the heater/ AC assembly (the big black box) About 6 inches from one of the metal tubes is the water control valve. I think you can see them if you take off the side access panel to the console (my entire console is currently out, so I don't remember what side)

If you look in the "spare parts catalog" (which you did purchase, right?) You can see an illustration at the lower left corner of the page showing the two tubes and the connections. The water tubes actually exit the tunnel on the passenger side of the car.

The non-AC cars may use a cable rather than a vac controlled valve but it's the same basic principle. (good chance if it's the original valve, it's probably bad by now)

Hey, Barry:
Do both sides of your center console come out by themselves, or is your RH side "core" clipped to your front "core" and covered by one section of vinyl? The latter is the way mine was, and it was really frustrating.
Just curious, mine's one of the earlier cars and I wonder if they changed it later.

Nope, they did not change it even on the 2nd series Monte. The left panel is easy to remove, but the one on the right side is connected to the front of the center console. (And the heater control is indeed behind that one.)

[ecohen2]

So the best way to get to this valve is from inside the car and not under the car? If this is the case, my life just got much better. The garage floor of where I am working on my car is FREEZING even when laying on cardboard or other material.

I am going to pull the passenger side panel off and see if I can find it. I had the drivers side off and tried to find something that looked like it, but never found anything.

Thanks,
Ed

Ed,

Nothing under the car that will help you. It is the left side that comes off easily, removing the right side involves removing the entire console (and of course the control is on the right side!). Once you have it off, you should be able to trace the two hoses from the metal water pipes to the heater core. One of them will have a valve inline. I'd guess that in your case it is a cable operated rather than vac operated valve. Please post your results for the rest of the class. I think the majority of US Scorps were A/C cars.

Thanks... Ill try and take some pictures while I am doing this...

If it's any encouragement Ed, look at the bright side- you could be messing around with a heater valve on a 164, or rather the flapper/stepper AC whozywhatsis- the one that basically reduces a car to scrap value when it goes bad!

[ecohen2]

HAHAHA I know exactly what you are talking about!

Well tonight is going to consist of cleaning and waterproofing the alfa top while taking apart the Lancia heater valve...

Fun times!

Hey, Ed

Just had to say that if your avatar is supposed to represent the wipers on a Scorpion, they're moving too fast.

:roll:

HAHAHA don't mind DJ, he probably just has one of those new-fangled Pentium computers! Looks fine on my 486! (OK, just joking!)

That is what you think! Actually, what is missing is the huge crack around the mirror.

I found that avatar... Thought it was good considering this is not my favorite time a year.

Just for the record, it's a Hewlett Packard Lance Armstrong "Livestrong" Special Edition notebook with a 2 gigaHertz AMD 64 bit Turion processor and 2 gigs of RAM. Bought it special for my new job cuz I need to run really large project plans. Out of the nuclear biz once again. Now "DJ the Cable Guy..." :D

New Lancisti site coming soon guys...

Hi Ed,
it's the easier way to remove the glove box to get access to the hot water valve then the whole console. Less work and better access. Only the glove box light wires are a bit fiddly.

HEY I NEED THAT WINDSHIELD!!! If that is what that is....



Well, I had to go to California for work... Ill give this a try over the weekend...

I have 2 Scorpions one with AC so the heater valve is vacuum operated and one without AC so the heater valve is cable operated. If your non-AC car (non push button) is hot all the time my guess is the cable sheath anchor (a screw and clamp) cam loose and the cable sheath is moving along with the cable so the valve is not moving. I would try to fix it without removing the center console. First remove the glove box. Do this by unscrewing the bolts that pass through the top of the glove box. Unscrew them from inside the glove box. You may have a small bracket just to the left side of the glove box box also. After you have removed the glove box remove the panel on the left side of the center console, this will allow you to shine a light into the center console. Get on your hands and knees, flip over on your back and climb down into the passenger side (Scorpion) footwell, look towards the very back (front of the car) of the center console. The valve is there. There are 2 hose that come up through the center tunnel and feed the valve. Move the lever and see if the valve moves. You can pull the side of the center console away from the center tunnel quite a bit to gain access. Determine if it’s a cable sheath moving or the inner cable is kinked. Fix it and then call for help in order to get out of the footwell.

It might help to pull the two rubber wedges from the wire loops under the front seat cushion, then the front lifts up and the cushion comes out 1-2-3.
Saves wear and tear on upholstery as well as lumbar discs.
