I promised more info in my thread for help, which ties to this thread. Just went through my flexalite controller going out. The original worked great for 5/6 years. Went through 4 new one's (original black box) and couldn't get 1 to work right. 2 were irratic in their on and off temp's. 2 would cycle perfect while idling, but when driving slowing around the neighborhood they wouldn't come on to the point of the truck getting to hot. Using my factory gauge, a temp gun and my full sweep Autometer electric gauge they all verified the fan was suppose to be on. Everything checked good, bulb contact, location, wiring and cap covering tip.
I was at a loss and decided to call flexalite and talk to AJ. He suggested checking for air in the system. Good call but I hadn't been in the cooling sytem since changing the coolant a 1 1/2 ago. Checked anyway and it's good. Reported back and he sent me controller #4. Worked idling not moving. For the life of us we could not fiqure out why. I spent a lot of time changing temp. settings and trying them out. (This was a lot of work between 4 controllers.) Maybe just a manufacturing problem? Anyone have any idea's what could've been going on? My truck was down for awhile waiting on part's. Told AJ I was done with this controller and needed my truck up and running.
I'll have to say Flexalite has Great Customer Service and Support. AJ stepped up sent me
Everything I needed to change over to an inline set-up. What more could you ask for? There was no warranty involved for my set-up and they still didn't hesitate in helping me out and getting me back on the road. I'll have to say on a 1 to 5 star rating on customer support I have to give them a 6. lol So if you have a Flexalite set-up your in Great hand's with them.
I also added a Fan Override switch and light for when the fan is on. (This is how the help thread ties to this one.) New set-up work's great and problem solved. Sorry for the long thread but you guy's need some more thread's to read. lolol Also wanted to thank AJ and Flexalite for all their help.
I know you guy's like pic's to here's a couple pic's of the new set-up and custom switch holder to match my center bezel.
