Scott, The Fan Fix,,, that I designed uses mininal parts, one special relay and allows the fans and compressor to operate the way they were designed to do, but not thru the main relay as to draw the voltage down on the whole car. They go on and off as the compressor desires. Plus I have addressed the low voltage problem at the same time, and the light comes on as power goes to the fans just reverse of the way the light was designed. $55.00 With the light fix included. This design is simple, no overheating and should last a lifetime. I would replace the circut breaker with a self healing breaker 40 amp if it's not already. That is $4.50. If your fans are old and have been use a lot then they will draw more current. I can normally replace the brushes and clean the armature to lessen the current draw. John 11004 6935 6568
