My 2000 Sable starts blowing hot air about every 6 months. I mean like an oven. All I do is disconnect the battery negative terminal for about 5 minutes. After I re-connect the problem is solved. This solves many problems on this car, it just needs a re-boot. It must be powered by Microsoft (ha ha). Good luck. ps my auto headlamps never did work right either. Dave.

You need to have your GEM module reconfigured after battery disconnect. It controls many functions. It may have also been damaged during battery change due to a voltage spike. Dealer can test it. Call a dealer service dept and describe symptoms and see what they say.

Module Controlled Functions NOTE: Prior to removal of the generic electronic module (GEM), it is necessary to upload module configuration information to the scan tool. This information needs to be downloaded into the new module once installed. For additional information, refer to Section 418-01 .
NOTE: Electronic modules are sensitive to electrical charges. If exposed to these charges, damages may result.
The generic electronic module (GEM) is the only multi-function module on this vehicle.
The GEM constantly monitors its subsystems for concerns. If a concern is found in one of the subsystems, the GEM will record the concern in the form of a diagnostic trouble code (DTC).
The ignition switch position is very important to the GEM functionality Erratic or unexpected GEM functions can often be traced to problems with these GEM inputs.
The GEM controls a variety of systems:

  • instrument cluster warning indication and chimes
  • interior courtesy lamp control
  • automatic headlamp control
  • daytime running lamps (DRL)
  • wiper and washer (front only)
  • heated rear window
  • one-touch down power window
  • delayed accessory
  • power door locks (including SMART, autolocking and luggage compartment lid release)
  • remote keyless entry
  • perimeter anti-theft

2002 mercury sable ac not blowing but heater works any ideas?


Could be a blender door issue. What a blender door does is mix the cold air from the AC with the hot air from the heater core. If you put the switch ALL THE WAY to hot, the blender door (usually an actuator) pushes the door up and allows only air passing thru the heater core to enter the cabin. If you push all the way to cold, it only allows air from the AC. If you put halfway, it mixes/blends the air...

open the hood,run the car with a piece of card over the rad (if poss)until its really hot then,with your sleeves rolled up and NO tie,look for a steam jet,if its hot enough, you wont miss it.unless it the heater matrix.but you would smell that inside the car with steamed up windows.(no ac)

Air conditioning doesn't work. only blows out hot air


Check and see if the clutch on the front of your compressor engages. If not it could have a leak and not have any freon in it. If it has freon then you have an electrical malfunction on the ac system.

AC blows hot air but AC compressor works


if the compressor works and your freon is charged it may be the blower flapper door....disconnect battery for 10 minutes and then re-connect to reset the electronics that control the flapper
