Re: No power in AC system except recirculate light
The Control Module In The Dash Is Known To Go Bad. These Can Be Found For As Little As 29.95 And Up to 500.00 Plus The Cost Of A Vw Tech Install But Can Easily Be Done Yourself By Plugging In A Wire Harness And Hooking Up The Wires For The Temp Control And The Defrost Selector.

code p 0403 refers to exhaust system gas recirculation (EGR)---circuit malfunction====causes wiring---EGR solenoid ---ECM
code p 0089 refers to fuel pressure regulator---performance problem===causes fuel pressure regulator---mechanical fault
as you indicate smoke , that would be black smoke , so that indicates a problem in the pressure regulation making the injectors pass more fuel ( flooding) than the ECM cam control
The end result can be blown seals at the injectors or injector problems
at this point replace the pressure regulator, then consider the EGR solenoid
If the air flow cannot be controlled from vent/defrost/floor you may have a blend door issue. This is an electric motor that operates a door in the heating system to control airflow. There are usually 3 motors controlling airflow direction,heat and recirculation. The Ac not blowing cold may also be another problem. If the AC is operational, the compressor will be engaged and the Ac low pressure line under the hood will bw cold. If this is all ok then a blend door issue should be suspected
sensors......Water temp sensor, air flow temp sensor, MAP sensor, Idle speed control solenoid, throttle position sensor, O2 sensor.........
Engaging AC draws on power from your motor, resulting in the ECU having to compensate to keep revs stable. Increased revs result in increased air flow, water flow, fuel flow & exhaust emissions.
Check belts for your AC pump first, as the same belt may drive your water pump. If it slips under load when the AC is on, ..................... Say no more. Next replace Water temp sensor. No luck..... ISC solenoid....

How to retrieve DTC:
The heater control panel has self-diagnosis function. To run the self-diagnosis function, do the following:
1.Turn the blower fan OFF.
2.Press and hold the recirculation control switch and the rear window defogger switch down.
3.Turn the ignition switch ON (ll).
4.Release both switches. The recirculation indicator and the rear window defogger indicators come on. The recirculation indicator goes off 3 seconds later and the A/C indicator comes on, then the self-diagnosis will begin. About 10 seconds later, the self-diagnosis will finish and the A/C indicator goes off.
- If any trouble is found, the recirculation indicator blinks the diagnostic trouble code (DTC) to indicate a faulty circuit or component.
- If the system is ok, the recirculation indicator stays off.

DTC (Recirculation indication blinks) Detection Item Page
7An open in the air mix control motor circuit.21 - 16
8A short in the air mix control motor circuit.21 - 16
9A problem in the air mix control linkage, door, or motor.21 - 17
10An open or short in the mode control motor circuit.21 - 18
11A problem in the mode control linkage, doors, or motor.21 -19
12A problem in the blower motor circuit.21 - 20
13A problem in the EEPROM in the heater control panel;
(THE CONTROL PANEL MUST BE REPLACED).21 - 38
14An open in the evaporator temperature sensor circuit.21 - 23
15A short in the evaporator temperature sensor circuit.21 - 24
- In case of multiple problems, the recirculation indicator will indicate only the DTC with the least number of blinks.
- In case of an intermittent failure, the heater control panel will store the DTC until the ignition is turned off.
BEST TO LET BMW DEALERSHIP REPLACE HEATER BLOWER IF NOT MISTAKEN YOU HAVE TO DISCHARGE AC SYSTEM TO REMOVE REFRIGERANT LINES TO REMOVE BLOWER MOTOR COVER.THIS IS NOT HOME FIX.BMW CARS NOT EASY TO WORK ON.YOU HAVE TO BE BMW MECHANIC TO WORK ON THEM.
AC COMPRESSOR KICKING OFF AND ON.SOUND LIKE REFRIGERANT LOW.LOW SIDE SHOULD BE 20 - 36 PSI AND HIGH SIDE SHOULD BE 215 - 310 PSI. AC SYSTEM COULD HAVE A LEAK WHILE YOUR COOLING STOPPED. DRIVER SIDE WINDOW MOST TIME SWITCH WILL BE THE PROBLEM.REMOVE SWITCH SEE IF POWER GOING TO POWER WINDOW MOTOR.YOU HEAR WINDOW MOTOR TRYING TO WORK WHILE USING SWITCH.WINDOW REGULATOR COULD BE BINDING DAMAGED OR NEED LUBRICATING.OR MOTOR NEED REPLACED.IF POWER NOT GOING TO POWER WINDOW MOTOR THE CONTROL SWITCH IS BAD IF ITS THE ONLY SWITCH.TO TELL IF WINDOW SWITCH IS BAD SHAKE POWER WINDOW SWITCH WIRES WHILE OPERATING CONTROL SWITCH.IF POWER WINDOW WORKS YOU KNOW SWITCH IS BAD.TAKE CAR TO AC SHOP BECAUSE LET THEM CHECK AC SYSTEM BECAUSE IF YOU BUY 2 CANS OF R134 REFRIGERANT. AND YOU TRY CHARGING AC SYSTEM YOUR SELF AND ALL REFRIGERANT LEAKS OUT. YOU GOING TO BE OUT OF $30.00 STILL NO AC.THAT WHY ITS BEST TO LET SHOP PUMP DOWN AC SYSTEM CHECK FOR LEAKS BEFORE RECHARGING AC SYSTEM.

Blower Unit Components Replacement
Note these items when overhauling the blower unit:
The recirculation control motor, the power transistor ), the blower motor (C), and the dust and pollen filters (D) can be replaced without removing the blower unit.
Before reassembly, make sure that the recirculation control linkage and doors move smoothly.
After reassembly, make sure the recirculation control motor runs smoothly.
yes the heater controls are vacum however the blower motor is not. a new control panel is an option and may fix it. if it was my blazer i would first check the fuse boxes onder the hood and in the side of the dash driver side. if they are good i would go to the nearest auto parts store and buy a test light. this will aid you in making sure what the problem is before you go spending money on replacement parts. the blower motor is in one of two places. its most likely under the dash on the passenger side. there is a cover that you will have to remove directly under the glove box. once removed you should see a large red and a large black wire. these are the power and ground for the blower motor . in some gm's these wires go into a resistor. the harness plugs into the resistor and the blower motor wires come out of it. ok now that we are a little bit familiar with our suroundings the red wire i told you about is the hot wire if you ground the clamp on the test light to the door hindge. (make sure its a good ground by touching the positive batter terminal. if the test light lights its a good ground )now unplug the blower motor and touch the metal posts in the end of the plug that belong to the red wire. if it lights when the key is on and the blower control is on in all posisions you need a blower motor. if it does not then you need a blower motor resistor.
