i'm leaning towards a short but have not found it yet . the rec and the ac lights are not lit meaning can't read any codes but will try the B 1. i did find another box and tried it but same results blower running on high and nothing else works. still looking

climate control is automatic and i'm still lookin for a cause of the problem

all fuses are good i'll look into the fan resistor, but would that keep the ac and rec control switch and idicators lights from working also thanks i'll look into it

Problems with 93 850 climate controls: no indicator lights at all, blower runs at high speed and will not shut off. not sure what is wrong but it started smoking and blower started running at high speed can,t find anything burned got new climate control and no change help
