AC Leak

Cap it off.

Cars have been made with only front AC since they started making cars.

Your back seat passengers wont even notice, as they expect the back to take longer for the cold air to get to them.

(but you might want to get a second opinion about where the leak is) 1500 sounds a little expensive for an A/C line

This is coolant leaking from the heater core ?? big job i'm afraid ?

The blend air door was the problem. You only have one AC unit in the car. If the rear was working, the system should be fine. However, the blend door will cause you to get heat if it is stuck in the wrong position, so I feel they were correct with that. IS the AC working properly now that you have it back?

EATC MODULE SELF-TEST The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated. 1. To enter the self-test, press OFF and FLOOR buttons simultaneously then press the AUTOMATIC button within 2 seconds. Display will show a pulse tracer going around the center of the display window. The test may run as long as 30 seconds. Record all DTCs displayed. 2. If any DTCs appear during self -test, follow the diagnostic procedure given under ACTION for each DTC given. 3. If a condition exists but no DTCs appear during the self-test, see SYMPTOM TESTS. The EATC system is Inoperative, Intermittent or Improper Operation. 4. To exit self-test and retain all intermittent DTCs, push the blue (cooler temperature) button. The control will exit self-test, retain all intermittent DTCs and turn OFF (display blank). 5. To exit self-test and clear all DTCs, press the DEFROST button. The vacuum florescent display window will show 888 and all function symbols for one second. Then, the EATC control assembly will turn OFF (display blank) and all DTCs will be cleared. 6. Always exit self-test before powering the system down (system turned off). Intermittent DTCs will be deleted after 80 ignition switch ON cycles after the intermittent condition occurs. NOTE: The EATC module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A scan tool must be used to retrieve these concerns. The EATC module self-test will detect concerns in the system control functions and will display hard DTCs in addition to intermittent diagnostic trouble codes for concerns that occur during system operation. The vehicle interior temperature should be between 40 °-90 °F (4 °-32 °C) when performing the self-test. If the temperatures are not within the specified ranges, false in- car temperature sensor DTCs will be displayed.
Post the results.

Was the clutch replaced with the new compressor? Are you getting power to the clutch? Does the compressor cycle on and off at all?

The clutch is usually part of the new compressor, so chances are they are being honest. To check for power, there is a single wire that runs to the compressor clutch. Use a test light or amp gauge to see if there is power to it.

NOTE: Please be careful near the pullies and belt.

Let me know what you find.

The relay wouldn't cause the fuse to blow. You have to have a short to the compressor.

Yes, I understand. It sounds like there is a problem with the blower motor. What needs to be done is this; when it does not work, you need to check if the blower motor is getting power. You can use a test light to check.

(There is an excellent post eight entries down)

Honestly, I would think it has to do with a bad ground, but I would have to check it. If there is power to the motor and it does not run, either the motor is bad or there is no ground.

As far as the cost, the motor will be under a hundred dollars from a parts store. The labor should be no more than 1.5 hours.
