Hello, WTB as in the topic - need rubber port, or whole programmer unit, but WITH THAT RUBBER. Rubber should be soft and not damaged, of course. I know I can bypass that port and connect vacuum lines directly to the unit, but I'm trying to keep my Riv as original as possible. Thank you
I posted a pic of the 71 Riviera in the local yard here......I can see if it has the same part....check out the pics to see if you need more parts.
Thanks for the link . No, as interior is another color, I do not need other parts. I was thinking that maybe the temperature control panel (left side of the driver), but that one is missing, so just Delco programmer, if it is there.
Hi, Here are picture of one I have, it seems soft and ply able with no cracks or splits. I'd like $25 plus postage. Thank Bruce
Hi George, Here's a picture of the only vacuum pot I can see without disassembling something. Where are the ones you are looking for. Thanks Bruce
Hey Bruce, you are right, looking under the dash form the passenger side, you will see only one actuator on the right side of the car, that in fact is not installed on the AC/heating control box unit (as i remember this one is for the air recirculation). And I believe this one is on your picture. Generally there are 3 types of vacuum actuators (+ heating vacuum control valve, but this is not what we are discussing here): 1. Air recirculation, stamped number 1998985 2. Air flow flaps control, with dual vacuum connection, stamped number:1998980, marked green at the following pictures 3. Air flow flaps control, stamped number 1998981 - there are two of them installed, marked red at the following pictures The last picture above, shows the position how the unit is installed inside the car. I know that it will take some work for you to disassemble all of it, so my proposition is that I could buy all of the vacuum actuators from you (if they are in working condition of course, so you should test them after dismount - apply vacuum and check if its moving). + I can purchase from you the AC control unit, marked yellow below (in Buick manual, named "programmer"). As you will not be able to test the control unit, then it is my risk if it is operational or not. And finally, I'm also thinking about the AC control panel with all the "spaghetti" behind.... Please be careful with the vacuum colored rubber lines (tubes), as I would also like to get them, if the rubber is in acceptable condition. The tubes are routed from the AC control panel, to the AC control unit ("programmer"). On some of the lines, there are silver labels "Caution, inline bleed valve" - please try not to damage them.... Am I orthodox ? ;-) OK, Please let me know how much $$$ you would like to get for all of these items. Thanks
Hi George, Is there an easy way to remove these items ? I think I know the answer. Pull the glove box liner, pull the dash pad and go from there. Are you in a hurry for the items? Thanks Bruce
Hey Bruce, it is a bit of work: indeed it is necessary to remove glove box, but no need to remove dash pad. For easier access and work, I did removed the passenger seat. Also removing the ash tray helps. From engine bay side, you must remove 3 nuts (marked yellow below) and heater core hoses. The rest are small screws (green) and one bolt (yellow) from inside area: And I'm not in big hurry, but what do you think, how much time you need get the items out ?
Hi George, A couple of questions, do I need to take the top duct out, seems it's held by something I can't see. I think I need to get it out to undo the top bolt on the heater core cover. Do I need to take off the heater hoses . Thanks Bruce
Hi Bruce, Here are the links to the PDF Buick manuals, where you can see the drawings of the system (usually at the last pages, ie. end of each document): https://docs.google.com/open?id=0B5B9cSOKg0m7WkpwbGRhMWpSVC1MZFpTSERzSm9yUQ https://docs.google.com/open?id=0B5B9cSOKg0m7bHROSjV3VjFUekNibDVRS0pJUF9zUQ https://docs.google.com/open?id=0B5B9cSOKg0m7WlVzUno4RXRUTVNIRUxxRUJaTUphUQ I was able to remove the unit without disassembling the top duct system - I had to remove only the air hoses directly from the unit, plus some plastic covers (from the unit), the rest of the top system remains untouched. You need to remove the heater core water hoses from engine bay area and remove 3 nuts, then from interior area one bolt (passenger side, bottom of the unit) The rest - what I remember - are small screws that are holding the plastic parts to the unit Put some force to the unit, as it can be "glued" to the firewall insulation - I was able to move the unit at its location this way,and carefully check what else needs to be disassembled. Remember, that two vacuum lines are going to the back of the unit (looking from inside of the car), to two actuators: Routing of the vacuum lines is also shown at the linked documents above. Also, here is a lot of informations: http://www.v8buick.com/showthread.php?209787-How-To-R-amp-R-Heater-Core-in-71-74-Buick-Fullsize George
Hi George, Thanks for the information. I'm not quite ready to drop the antifreeze out of it. It still runs and drives, it's a lot easier to move around. We're support to get a couple of hard freezes this week. Your going to have to give me a couple of weeks before I get it to that point. Thanks Bruce
Hey Bruce, no problem, I'm not in a hurry. However, if you have a vacuum controlled heating valve from other GM car, you can use it as bypass (linking two heater core hoses together). I did it, as this way I can also move the car around my yard ;-) Bruce, your private message inbox is full, so I can not answer there. Therefore my answer is here: I would like to take also the front plates visible at the pictures: http://s1178.photobucket.com/albums/x377/buickjunkie/72 Riviera/?action=view¤t=4d2ebd91.jpg http://s1178.photobucket.com/albums/x377/buickjunkie/72 Riviera/?action=view¤t=0ed0ca3b.jpg + clock + radio Looks like the rubber floor mats are original ... Maybe you could took a picture as well, so I will see condition of them ? Please let me know how much you ask for two front plates + radio + clock. Thank you !
