So, my heater has never worked very well, but it's not a winter vehicle (92 Geo Tracker 1.6l 8v soft top) so I haven't cared much. However, one day the blower motor just stopped. One thing led to another, and a new blower motor + resistor fixed that. BUT: the heater controls are messed up. I think someone tried to fix a blockage (I hear that leaves building up in the fan box is quite common? - I did find some in there), and incorrectly connected the slider controls behind the dash. It's difficult to describe the results, but let's just say I'm pretty sure they connected the wrong cables to the controls. When I disassembled the fan box, I took some photos of the heater core and leaves are packed in there somewhat tightly. I vacuumed out what I could, but it's difficult to see and I'm not confident it's completely free of debris. Two things: a) I plan on replacing the entire dashboard (I have a replacement) so I'll be pulling it all out anyway (approx 6 hours from what I can gather). b) while I'm in there I plan on fixing the controls and cleaning any and all blockages in the the ducting. My question is: would it be worth it to just replace the core while I'm in there. I'm pretty sure there is a blockage in the fins that can likely be cleaned out, but I wonder if I should just replace the core now so I don't have to mess with it later. I'd really prefer to only take the dash out once!! So my question is more about reliability of the factory core. If they rarely leak, I could just keep the old one. Maybe pressure test it? I'm not sure what the limits might be. Anyone 'been there' who can advise? At the moment I'm leaning towards just swapping it out for a new one so as to have a bit of peace of mind that the factory core might leak and I'll have to do this all over again. Many thanks
