AC blinking lights 850 1994

when the dash is hot, our lights blink 17 times, but if the car is cold, this won't happen. doesn't matter if fan setting is 0 in any case.

everything functions great unless it is very hot (100+) then the fan operation is somewhat dicey and indicator lights in the instrument panel can twinkle and twitch, making me very nervous. the blower was replaced three years ago, but not the resistor. lots of codes are set but I don't trust that they really indicate the source. I could list them if that was helpful, but you've probably seen the list before.

temp sensors were replaced in 04 as well (near grab handles). how should I diagnose this? why don't the lights blink all the time? why does heat seem to make a difference? could this be related to my other issue - knock sensor signal absent or faulty (4-3-3)?

car is a 94 turbo wagon w/ECC and 150k.

thanks
matt
