Hi, read all the threads till I'm dizzy about cooling fan issues! Still we don't have one that gives you step by step instructions on exactly how to troubleshoot the problem. Wish we could get one. I did replace the two relays under the air cleaner but still didn't fix the problem. I also replaced the two wire sender. The fan does come on with the A/C though. What I want to do is wire up the high speed fan to run all the time. Then I won't have to worry about it. I read on one thread if you change a wire on one of those replacement relays the fan will run. Anybody know how to do it? The wife got a traveling job in the city and doesn't want to wreck her car so I have to give up my Scort! I guess it's expendable!
