El Chapo Posted July 7, 2022 Author Share Posted July 7, 2022 who dares wake me up? actually, you have a BROKEN ac vacuum port selector switch. if it were not broken then you would never have even seen said mystery part. I'm certain that I have one in storage but frankly I'm a mess right now. I'm in the middle of moving my shop 430 miles. I have not even begun to move the parts barn and I have to finish Ms. Anns house first or there will be no peace. I hope to be operational by the end of July as lefty is just covered in the shop awaiting metal work. and we are due in Louisville for the street rod nationals the first of august I believe you can get this part from parts geek if not lmc. rock auto should but their system sometimes puts these odd parts in places hard to find on the website. I did a check and Oreilly's shows it in their warehouse. motor craft part number yh380 for $99.99. I know that's not inexpensive, but it is a motor craft part. possibly look for that part available on amazon etc. Thank you guys I’m glad it still available, appreciate the help.

FuzzFace2 Posted July 7, 2022 Share Posted July 7, 2022 You can still buy new Motorcraft replacements for this part. https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=Motorcraft+YH380&_sacat=0&LH_TitleDesc=0&_odkw=1986+ford+bronco+a%2Fc+control+panel&_osacat=0 The link shows 83 to 91 so I guess the 80 - 82 is what I have as it is different where the AC / MAX AC / Vent is. I think mine leaks a little as to get the MAX AC to work I have to stop at normal AC first to get it to blow out the dash vents then can go to MAX AC. Also on MAX when I get into the throttle it goes to defrost a lot more then when on AC. Yes I have replaced the vacuum check valve and it did not help.

Dave ---- There was actually a difference in 1983, and I'm thinking it was the vacuum port switch, but I'm not 100% sure. I do know that the interior A/C control parts are generally considered 80-82, 83, and then 84-86. Link to comment Share on other sites More sharing options...

Yes it supposed to be motorcraft YH-360 description calls it out as a “damper door switch”? Looks identical to what I’m replacing so yeah we’ll find out like in three weeks what the real deal is. But that’s why I buy from Amazon as much as I can - free returns no hassle. Sometimes a crap shoot fine if you’re not in a hurry. Should I cancel if it’s not suppose to be a damper door switch?

I was looking it up and thought the part number was yh-380 but I look things up because I get numbers mixed up a lot. PINs and passwords are my biggest problem, but part numbers are an issue also.

Was that just a typo and it was really a 380? The YH-380 is for 1983 and later trucks with integral, meaning factory, A/C, as shown below. Link to comment Share on other sites More sharing options...
