Heat/vent problems
Okay so my truck blows heat but the driver side vent just shoots in ambient temperature air like crazy depending how fast I am going. Anyone have this problem before? Would suck once it actually starts to get cold!

Re: Heat/vent problems
Very interesting. Are the heater box seals leaking air around the box? Is the duct not attached to the rest of the HVAC unit?

Re: Heat/vent problems
most 720's the passenger and driver side vents are actually routed to induce fresh air, thats why they can be rolled to a closed possition. if it does not have stock a/c especially. they route to the acess pannel where the wiper likeage is located. strange pain in the butt but thats how they made them 
(same thing on all but one of my 4 nissans from 1982-1985 in which I have pulled all dashes atleast once) you could either find dash parts from a nissan with a/c to reroute the heater lines or seal them off from the access pannel if they become too big of a pain, or slap any passenger that tries to mess with your vents in the middle of winter
