I'll make this to the point. Summer day and the ac stopped blowing out. Checked fuses etc. Wouldn't blow in any speed, figured blower motor. Replaced and still nothing. Replaced resistor, works on 1,2,3&4 better but shuts off after a certain amount of time. Figured wrong resistor p\n 970353D000 could my troubles be because I need the 9703508000 kis soul resistor? Could it be a relay? My model has manual heat setting and auto ac. I'm confused at this point...
