james curl Posted January 2, 2008 Report Share Posted January 2, 2008 Norm, I see from the picture that you posted of the relay under the hood of your car that you have a heater on the drivers side as I can see the hoses in the picture. Does the coupe have two heaters? Where does the heater sit on the drivers side and not be in the way of the clutch and brake pedals? I know that it gets cold where you live but I would think one heater would heat a coupe. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted January 2, 2008 Report Share Posted January 2, 2008 Besides the heater..what does the toggle switch in front of the relay operate? Quote Link to comment Share on other sites More sharing options...
55 Fargo Posted January 4, 2008 Report Share Posted January 4, 2008 James , one of the Chryslers I have(the parts car), has the dual heaters. It does a few more things then just add heat, you have it connected to the fresh air intake, this allows you to add fresh air in the cold times as well, this may help with keeping the inside from being stuffy. It also will let fresh air run out through the heater ducts by the kick panels to the rear seat area. These type of fresh air set-ups will allow you to keep the cowl vent open in the rain, they do not allow the water to spray into and under the dash as the regular ones can do. Where I live it is plenty cold, but driving a collector car in normally warmer weather negates the necessity of really needing dual heaters. I presently only have one installed in my 47 Chrysler, maybe at some future point I will install both for purism sake. The 2nd heater mounts high enough under the dash in the drivers area, it does not interfere with anything or the clutch/brake pedals............Fred Quote Link to comment Share on other sites More sharing options...
bigred48 Posted January 5, 2008 Report Share Posted January 5, 2008 My 48 p15 sedan has dual heaters in it too. I think it was an option but I am not sure. Quote Link to comment Share on other sites More sharing options...
47heaven Posted January 5, 2008 Report Share Posted January 5, 2008 Man, who needs duel heaters? Just the one I have cooks me within five minutes. Sometimes if it's too hot, but I want to keep it comfortable inside (not too cold, not too hot) I open the cowl vent some and the regulates the temperature with the cold and hot air mixing. I've never opend the cowl vent up in the rain bcause I haven't driven in it yet, but have wondered what people used to do back then to let in fresh air when it was raining or snowing to prevent the windows from fogging, without opening the cowl vent or the windows so water wouldn't get in.

I reecall as a kid my mom or dad always had a window rag in the car. I carry such a rag in my car as I have not found a way to keep the windows clear in the rain.

48mirage Posted January 5, 2008 Report Share Posted January 5, 2008 My D30 has a summer setting for both the heater and defroster. I've never paid much attention to what that setting does, but I'll guess it lets fresh air in around the heater coil. Quote Link to comment Share on other sites More sharing options...
Norm's Coupe Posted January 5, 2008 Report Share Posted January 5, 2008 James, Fred explained the purpose of dual heaters. Actually, since I don't drive my coupe during the real cold months I usually don't have both of them on either. Just the one on the right side. The heater on the left side is far away from the clutch and brake pedal, so there is no interference. They sit up against the kick panel and high up off the floor. If you wanted to kick one of the heaters, you'd have to really try hard. TOGGLE SWITCH BETWEEN HOSE AND RELAY: That is actually the switch for an under hood light. Turns it off and on. Also have a similar one in the trunk. They were options/add ons for the period. Actually, the under hood light is about useless because it doesn't light up enough to really see anything. One in the trunk is nice though. They were both on the car when I bought it and looked like they were there from day one. Like Don Coatney mentioned, his parents use to carry a rag in the car to wipe condensation off the windshield all the time. I remember my parents doing the same thing in Louisville, KY back then also. However, with the dual heaters you don't need the rag. You can leave the cowl vent open when raining in the summer to remove the condensation. In the winter or cool months, the defroster seems to work better than the ones my parents had back then with the single heater. I don't need to carry a rag with me in my coupe for that. If the windows do fog up, the defroster will clear them off almost right away. So, there is an advantage to the dual heaters other than simply heating up the car more. The dual heaters are original factory options listed in the P15 and other Mopar parts books. Again though, my coupe came with the dual heaters so the original owner must have ordered it that way.

PatS.... Posted January 5, 2008 Report Share Posted January 5, 2008 On my Chrysler, if the cowl vent was open in the rain, rain got on the radio. The radio did not like that at all ;( My dad had a small fan bolted to the dash of the 46 Chevy, aimed at the windows to keep the fog off. Car paste wax will also prevent the fog from forming.

Normspeed Posted January 5, 2008 Report Share Posted January 5, 2008 You can crack the vent windows open, it seems to help. On my old VW I used this stuff, it helped a lot. Also kept a wiper rag handy. Quote Link to comment Share on other sites More sharing options...

cwcars88 Posted January 6, 2008 Report Share Posted January 6, 2008 I solved my fogged windows by picking up a 12-volt fan from the local parts house. It is about 6", has a wire cage around the fan blade, enough wire to go to the dash and a low-off-hi switch. 6 volt system so I run it on hi and it does the job. Keeps all windows clear. Its just laying on the package tray, pointed up at the rear window. I live in Washington state lots of rain and mosture. My daily driver.

Norm, what can I say...you're just a preservationist at heart. Yup, sold my last VW bug around 1987, and this was an old bottle even then. Darin, I'm real pleased with the heater valve I installed, like the original Norm's. If you ever want to tackle that for your car I can help. I managed to hook mine to the original heat control cable. Quote Link to comment Share on other sites More sharing options...
DonaldSmith Posted January 6, 2008 Report Share Posted January 6, 2008 My dual heater setup has the cowl vent to let air in to the plenum and from there into the heaters or to the cabin. A "weather door", operated by the smaller of the two levers under the dash, lets fresh fresh air from the plenum directly into the cabin... "Danger, Will Robinson!" Rain will get in through the weather door if it is opened when the cowl vent is open. And the radio is right in the way. I put a plastic shield over the back of my radio when I reinstalled it. (The plastic also protects the circuit breaker I mounted no the back of the radio.) Also vulnerable below the weather door is the carpet. I made the mistake of washing the car with both the cowl vent and weather door open - once. Had to pull up the carpet to get it dry. The plenum has a drain hole at the bottom and a hose under the hood. I made sure the hjole and hose were clear. The elbow was corroded shut, so I replaced it with a copper elbow.

If you ever want to tackle that for your car I can help. I managed to hook mine to the original heat control cable. Norm...but my valve is the hand crank type. Don't you need that special valve to be able to connect it to the heat control cable? That would be nice, though. I am missing the mechanism that serves as the pull for the heat control or was that just a cable? Quote Link to comment Share on other sites More sharing options...
Normspeed Posted January 6, 2008 Report Share Posted January 6, 2008 You just need the universal valve that rockauto sells, and a cable control. Norm had a photo on his website of how he rigged his up in his P15. You can put it inline anywhere in the heater hose from the block. If your control cable will reach it, you're set. I put mine near where the factory valve used to be on the firewall so my control cable ended right there anyway. Quote Link to comment Share on other sites More sharing options...
