Funny thing about the K5 with no top... No air to speak of comes in. You'd think you would freeze to death, but the air just blows over.... My heater fan makes noise so I have to leave it on low.... I replaced the fan itself but may have gotten it in there cockeyed or something. About 20 years ago an old guy showed me how/where to drill a hole in that blower motor and put a few drops of 3 in 1 oil into the hole. It lubes up the motor and stops it from making that noise (I'm sure you all are familiar with that noise as these trucks were bad for it). You don't have to replace it or even remove it. Pretty neat.
Nope, it wasn't cold that day... It was in the 70s! A light jacket was all we needed!
Thanks guys!
