I'm having a similar problem with fan speeds 3 & 4 and I already changed out the blower motor. Also my car dies sometimes when stopped at a light, at night with my lights on and the AC is actually working. The AC is fully charged and the fans continue to cycle often. Am I experiencing two separated problems? Does anyone know the difference between the "Fan Fix Dual 2x2", the "Fan Fix One" and the "Fan Fix Two" from http://www.specialtauto.com? Do they all do the same thing? If they do, what is the advantage of paying $129 over $55? Would I still have to replace the circuit breakers and relays if I get one of these products? -- Warren VIN 2140 >You need to order a relay upgrade kit.
