I am having the same prob defrost works on all the settings i already fixed it once a hose broke on the firewall and i just replaced it you should not have to take your dash out look under the hood at all the vaccume lines on the firewall

Well everything works except ac cuz the combination line is falling apart and leaking but I'll check the lines mentioned for leaks
