Title: Blend door
Post by: Harmon on June 02, 2013, 10:24:20 pm

My blend door isnt functioning correctly.  Is there a schematics or diagram to show how the cables/vacuum lines should be?  I have the glovebox out now so I can switch the door by hand to the open posistion to have air flow out of dash vents.

Flip to page 1B-20 (pg. 83) of the 86 Service Manual (http://www.73-87chevytrucks.com/techinfo/7387CKMans//Service/X8632_1986_GMC_Light_Duty_Truck_CK_G_P_10_to_30_Service_Manual.pdf).  It takes several minutes to download from the site, so be patient.  Save it to your hard drive for future reference and faster access.

If you need any other information, additional factory manuals are available in our Technical Pages (http://forum.73-87chevytrucks.com/smforum/index.php/topic,25639.msg213706.html#msg213706).
