84 Suburban Heater Issues
I've been doing a little work on my brother's 84 3/4 ton 2wd Burb. The heater isn't working quite right and I'm not quite sure what to take apart. The problem I have is when the control is set to defrost, air is still blowing out the vents in the dash and a little is blowing out the defroster vents. It is an AC truck and I'm pretty sure it is getting good vacuum. Where is the part I need to check? I tried searching, but didn't really find anything. Any help will be greatly appreciated. Thanks!
