EATC Self Test
I’ve tried to do this test (floor/off button then auto within 2 seconds) and nothing happens tried checking software version (floor/off then max ac) nothing came up there, the Eatc run blower fan only at high speed the temp can be adjusted up and down but all I get is hot air out off any off the vents I’m leaning towards the Eatc being the culprit and other suggestions. 1995 Eddie Bauer

ok I got the self test going it came back with no fault codes just the 888 at the end to say test is done, so here is what’s happening turn on eatc to auto and put on max ac no cold air turn off ac get lots of hot air even with temp set to 60degree F, no low speed fan in manual just high and same in auto no low speed fan just high speed
