ECM arrived programmed with the wrong… ECM arrived programmed with the wrong year after supplying them with the VIN # Drove about half a mile and ABS light and brake light came on. Also the rear defroster light started flashing and the A/C light will not come on and I can’t change the position of the blend doors for the heat. It only blows out at the position where it blows air onto your face. Very disappointed . Very disappointed. I returned the ECM immediately

Jeep Grand Cherokee 2007 worked PERFECT I have a Jeep Grand Cherokee, 2007, which are known to have ECM problems. I send my vin number to them, and they send me a programmed ECM specifically for my car. It really works ABSOLUTELY PERFECT. It was really plug and play. I did print out the instructions, on how to install it for my mechanic, and he installed it exactly as described. He didn't even need a scanner, since when it was placed, and after the soft reset, it worked immediately and perfect. I am so incredibly happy. Thanks guys from MAKS, my car drives like a new one!
