Module is definite suspect. Where are U located? Is it starting to get hot outside? Here in the Sonoran Desert tomorrom it will be 101 F. & that's when Modules start to Dump! Ford in 70's played games with 5 different "Heat Ranges" of Modules & the only one that worked was coded "Blue" in color of the plug. I'll see if I can find out more on that for U. Also, Un-plug all the connectors & clean with a "Contact Cleaner" then use an "Electrical Grease (Dialectric)" on them. I have seen this cure Lots of Problems.   John
