- Welcome! This video marks the beginning of a new series I call For Your Information. As the name implies, these videos don't have a repair or maintenance in them but instead are informational videos about how something works.
In this video I go over the custom AC installation in my Starcraft converted 1997 Ford E-150 Econoline name Enigma. Unlike the Ford rear ac installation, Starcraft turned to another company called ProAir to install the rear AC for their vans. In the video I cover where the rear ac is, how it works and where to find all the pieces of it.
I would like to note that I say condenser multiple times in the video for an AC component when I meant to say evaporator.

Thanks for the video. 2001 conversion van, and my vent was only blowing hot air, tried to open the top part and was looking the damper door like in other bigger Ford Van Models. Thanks to you i found out that l, the heat is regulated by the valve from the coolant.
Yeah, the conversion vans all went to that setup for some reason instead of the dual blend door setup that Ford did. Glad the video helped.
Woa ! Dude ! I have a 97 Ford StarCraft conversion van ! I've been trying to find this information for the last month ! Front blows nice and cold but the rear blows warm . This is the exact information I needed ! Been finding a lot of broken and rotted vacuum lines . That might be part of the problem . Also I might just disconnect the heater coolant hoses to the back temporarily and see if that works to get cold air to the back . Awesome video ! Just what I was looking for ! Yup . Just confirmed . Have no vacuum to the line in either hot or cold setting . Time to start tracking vacuum lines !
So the key to getting the vacuum signal is not in the blend door (temperature knob) but in the mode knob. I think you are supposed to get signal on any of the ac settings and defrost. On my van the vacuum line runs down into a grommet near the driver's seat before it moves down the frame rail to the coolant bypass valve. Once you get the vacuum sorted out if the back is cool but not cold, you probably have a bad expansion valve. There's another gentleman I'm talking with that has the same style rear AC and he is waiting on results from the mechanic he found that is willing to work on it.
Bro, what do I do with this vaccum hose. I seen the same hose on your pro air system but I don't see a spot to connect mine
great videos, where do you think you can find part for this rear ac unit such expansion valve, resistor etc?
The expansion valve can be found most any car part store, amazon, ebay, etc. The rubber line is standard 3/4 inch heater core line, that's not hard to find either. The blower motor, fan and the combo evaporator/heater core unit are rare. Pro Air (I think that's the company) is still around and the have the unit for sale at their website. It was $600 plus last I checked for the combo unit. If you are wanting to rebuild a rear AC I think it would be easier and cheaper to try and install the default rear AC system that Ford supplied if possible.
my 1998 van has the same set up. the front of the van has cold ac, the rear is hot. i cut my heater core lines and routed them into each other to bypass the core. now the ac is cool in the rear but not cold, what do you think could be the issue? my expansion valve gets cold and watery
Could be a few things. If your rear air is from Pro Air, that means you need a total amount of 58oz of freon in the system. If you are a little low, that could do it. If the expansion valve in the rear is wearing out, that would do it. That being said I think the system wasn't designed to blow ice cold. What little reading I have found about others with this system shows that even when it's 100% working right, the rear should be blowing in the low to mid 50's F when the front AC would be blowing in the 30's F. After completing repairs on my AC just a few days ago and refilling with freon, that is what I'm getting.
@@MazdaB3K thank you, im going to see my freon readings and ill pump 58 oz
Thanks so much for making this video. I have a similar system and I'm deleting the rear unit. I cut the vacuum line to the vacuum controlled value expecting to see wires (had not saw this video yet). does that mean I have a vacuum leak now? Thanks
Yup, that you do, but only when you move your AC control to Max AC essentially. It's a HVAC vacuum leak so it really shouldn't affect engine operation, but you may have some oddness when you are accelerating up a hill or under heavy throttle. Easiest thing you can do is put a nipple of some sort in the cut end, then cap the nipple. No more leak then.
At 5:58 in the video what are those two connections that the rear ac lines are connected to there's like two knob type of doo-hickies on there? I have metal lines going to mine on a 2001 ford conversion (no rubber) i accidently broke one of the line ends going into that thing this is a very hard thing to get imformation on Thanks
Those two hard lines are for the AC part of the evaporator/heater core combo my van uses. The bigger of the two is the lower pressure line and you see it has a fill port (blue cap) on it. As to exactly what the knob things are I'm not 100% sure. It might be those are caps covering a port for a cutoff switch where the sensor was never installed. I do know in my setup an expansion valve is used to meter the amount of freon that goes to the evaporator to control how "cold" the rear AC can get. I intend to revisit the rear AC as I think my expansion valve is a bit flakey but I haven't had time to troubleshoot it thoroughly. Hope my answer helps.
Do you know where I can find that “2 to 1” valve ? Not too sure what to shop for but my set up looks exactly like yours so I was gonna try and replace that valve as well- have the same issue
So, what I installed is not what was there, but it works the same way:
Ford F87Z-18495-AA
www.amazon.com/gp/product/B000O0DRDS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I intend to install this again as a bypass for the heater core to make the AC blow colder. I'll probably make a video on that. Need to do that in my F-250 as well...
@@MazdaB3K thank you, is it just antifreeze going through this valve or is it Freon coolant? I was able to find the original valve from what you said.
This valve is for coolant/antifreeze. If you have the same rear AC setup as my van they'll be two pretty standard coolant lines running under the driver's side near the frame rail and that's where the valve needs to go.
