Hey everyone, I have been searching this forum and others for the past few weeks and not had much luck finding the information im looking for. My grandfather has a 99 LX470 with 350k miles. His AC hasnt worked for a few years but last year I recharged it and it blew cold for a few weeks. He called me and told me it had stopped working so I assumed the refrigerant had leaked out but it was in fact not blowing air at all. The blower motor was squeaking really bad so i replaced it but still no change. I pulled out the cabin air filters and cleaned what i could of the evaporator but still no change. At max fan speed there is the faintest bit of air through the vents that does change when you change the modes so I think the mode door is working. I pulled the ECU out and can see the recirculation door moving when changing the mode and that does not affect the air out of the vents. Currently thinking there might be a blockage somewhere in the system but I dont know how to go about investigating. Do i need to pull the dashboard out or is there a chance I can fix it with it in?
