I own a 2002 Ford Taurus SES with a V6 3.0L DOHC
engine and 80,000 miles. Recently my wife was driving the car pulling onto the highway when she pressed on the accelerator and the car hesitated and jarred with a loud sound coming from under the hood, the car did not die, just hesitated. Since then, the check engine light has come on and there is a whirring sound from or nearby the A/C
compressor. When the fans are turned on, ever since the previously mentioned incident, there has been an odor coming from the vents. There is no smoke, just the smell of something electrical burning. Also, air conditioning has not worked in the 6 months we have owned the car. Heat works, but slowly. When the fan is engaged (on high) with the air being directed to the defrost, there is a slight variation in the rpm's, also in the A/C
and Max A/C
phases the rpms rise about 600 and if the vehicle is in drive and idling while the fans are running (with heat or cold) it generates enough power that i have to apply additional pressure to the brakes just to keep from inching forward. I brought it into a local auto parts store and hooked it up to a scanner and it spit out the code: P1633 Keep Alive Power Voltage too Low.
ok, so here's my thoughts...
I think the condenser clutch has a bearing out which could cause the alternator to work harder which could heat up the wires and cause the smell, while at the same time, the computer which is calling for the increase in power is also causing the engine idle level to vary. Just wondering if I'm on the right track with replacement of A/C
Any knowledgeable input would be greatly appreciated.
