    Need a Non-AC Heater Box

    Novice here. The heater core in my 78 Chevy K10 started leaking. I purchased a new core and began uninstalling the heater box under the dash to replace it. In the process of taking out the box, I snapped off the last two remaining studs. They basically just crumbled in my hands. The one at the...

    Surprise No. 238.2, and Thinking Outloud and In Writing

    Yeah, buying a rig nearly half way to being an antique is a pig-in-a-poke. Lots of fun things to do and undo. Things like, install the park-neutral safety switch wires, fix the washer pump, turn the wipers back into a "only on when the ignition is on" unit, install a horn, add the backup...

    Replacement wire for blower motor

    Hi all, I was wondering if anyone can tell me where I can order a new wire for my AC/Heater blower motor? The fan failed and the connections at the ends of the wires overheated and melted on the inside. See pictures for what I am looking for. Thanks in advance for your help!

    Heat

    My 85 has a/c which works fine. The heater will blow warm air for a few minutes, then it gets cool. There is no sign of a heater core leak. What this could this be? Since I get hot air for a few minutes, I assume the blend door is working. Could I have a problem with a vacuum line? I have never...
