Hey, everyone. I'm new, but have read through all of the forum postings about heaters that I can find. I found many related links. But none have quite answered my questions below.
P { margin-bottom: 0.08in; direction: ltr; color: rgb(0, 0, 0); }P.western { font-family: "Times New Roman",serif; font-size: 12pt; }P.cjk { font-family: "Droid Sans"; font-size: 12pt; }P.ctl { font-family: "Lohit Hindi"; font-size: 12pt; }I have purchased the heater rebuild kits from Shane (metrictlc) for the stock blower motor as well as for the stock heater assembly that is actually inside the cab. I haven't installed either kit, yet. I have a question before I install. Well, actually three questions. Here is my situation, followed by the questions:
A. I am getting plenty of heat already. Heat works just great when I put the lever into standard Heat mode (all the way down). The cold air vent doesn't blow any cold air when I select Heat. Well, it doesn't blow too much cold air; I figure that Shane's kit will fix that minor issue.
B. The vent setting works great - lots of cold air out of the top vent, as expected.
C. When I put the heater into Defrost mode, I get some heat out of the defrost vents. Not much, but it's acceptable, and plenty warm. Again, the defrost blows relatively weakly, but I do get heat and air up there.
But, the problem I am having is that even though the defrost works alright in Defrost mode, the middle vent spews out lots of cold air at the same time. And I mean a lot of cold air! This doesn't seem right.
By the way, the fresh air lever/cable works fine; I can open and close it, and have verified that the door in the firewall moves open and shut.
My three-part question is:
1. Is it normal/expected for the heater to blow out cold air in Defrost mode? It doesn't seem so.
2. Will the problem with the cold air coming out of the middle vent while the heater is in Defrost mode be solved by using/installing the rebuild kit? It might be that a bushing or two isn't working right, and the new ones - or new foam on the vents - will solve the problem.
Note: I will also clean the heater core inside and out.
3. Or, is there some other issue I need to address? For example, is there some sort of vent, lever or door that I need to check to see if it opens and closes in the blower motor, or something?
I'm thinking that the rebuild kits will do the trick. I just want to avoid getting frustrated if I'm missing some other function in the heater.
Thanks, everyone.
James
