What fuse goes to the ac/heater fan in a 2004 Buick Rendevous


https://s4.postimg.org/m2cv5i825/hvac.jpg

Click on the link
See ign fuse 3--40 amp toward the right, in power distribution center under the hood, it sends voltage to blower motor control module. The two fuses toward the left, among other places, sends voltage to hvac control module. I looked up info for automatic hvac. Are there any applicable hvac trouble codes? At the moment, I can't rule out the blower motor itself?

I have a 2011 Chevy equinox my air conditioning is blowing on the front windshield and not coming through the vents how do you fix that


Can you check for hvac trouble codes? Some of the national brand auto store will check some codes, for free. I don't know if they can check hvac trouble codes?
Note the diagram, the mode door actuator could have a problem? You can see the wiring circuits. I'd want to check those circuits before saying the actuator is faulty.
The radio/hvac control sends data to hvac control module and that module reacts accordingly.

Air/heater wont shut off


If the blower motor won't shut off, pull the blower motor relay in under hood fuse box. That should kill it till you find the problem. I don't know if you have automatic hvac or manual hvac?
Can you check for hvac trouble codes? Some of the national brand auto stores will check codes for free.
If blower motor wiring connector has both voltage and ground, it will run as long as the battery has voltage.
I saw two different wiring diagrams on your blower motor, I don't know which one applies?

I have a 2006 Pontiac g6 gt and my heat or air will not turn on or rear defrost


You have a computer controlled HVAC system ! It has the capability of setting DTC'S - diagnostic trouble codes !
The HVAC control module is a non-GMLAN device that interfaces between the operator and the HVAC system to maintain air temperature and distribution settings. The battery positive and ignition 3 voltage circuits provide power to the control module. The HVAC control module during defrost mode will change the A/C compressor LED status from on to off. The control head displays recirc, outside air, A/C and rear defrost feedback status through LED indicators. The control head has a rear defrost request switch please refer to Rear Window Defogger Description and Operation in Stationary Windows for operation. The HVAC control head will display NO COMMUNICATION when checking DTCs or doing a vehicle diagnostic system check refer to Diagnostic Trouble Code (DTC) List - Vehicle and Diagnostic System Check - Vehicle in Vehicle DTC Information.
The rear window defogger system consists of the following components:
?€¢
Body control module (BCM)


?€¢
Heating, ventilation, and air conditioning (HVAC) control module


?€¢
Rear Defog relay


?€¢
Rear window defogger grid


Your probably better off taking this to a ASE certified repair facility ! You probably have bad Heater / A/C control panel . HVAC Control Module Malfunction

P0161 CODE ON JEEP LIBERTY 2003


Posted by Anonymous on Jan 25, 2013
why post to 2013? ELIAS? why not start your own post.
and not mix, engine sensors with HVAC blower heaters. hark.
the OP never once stated cars drive line.
and matters 100%
my guess is a jeep liberty with 3.7L and 2.4L 4 banger.
the answers vary by engines.
so if 161, is set the heater in bank 2 is bad, rear OXY sensor.
O2 Sensor Heater Circuit (Bank 2 Sensor 2)
the pcm measures the heater current flow
when it reads zero the sensor is bad or the wire is cut.(or rusty)

guess 2, is that late poster thinks
P0161 codes are HVAC codes
no it is not.
P0 codes are USA federal base codes.
and are for smog not dash HVAC heaters.
nice guess but dead wrong.

in most cases the 02 sensors is just bad.
the heater inside it just burns open.
all do that , every one... not one lasts
the life of engine, ever.

here ill read it to you, the SM. for 3.7L V6
gas engine, USA book and car....

Trouble Code: P0161 (3.7L V6 VIN K Auto)
O2 (B2 S2) Slow Response

Number of Trips to Set Code: 1

CCM Details

Trouble Code Conditions:
ECT Sensor less than 147?F and BTS signal within 27?F of the ECT Sensor (cold engine), engine started, system voltage over 10.5v, engine running at idle speed for over 12 seconds, and the PCM detected the O2 signal was more than 3.0v for 30-90 seconds.

Possible Causes:

ASD relay output (power) circuit to the heater is open

O2 heater ground circuit is open or O2 signal circuit open

O2 heater element has high resistance, is open or shorted

PCM has failed

Need to recalibrate the actuator pulling out the hvac fuse b for 10 second


THE HVAC B FUSE IS LOCATED IN THE FUSE BOX UNDER THE REAR SEAT. IT IS FUSE 36. CLEAR ANY CODES FIRST. REMOVE THE FUSE FOR 10 SECONDS, REINSTALL THE FUSE, START THE ENGINE, WAIT 40 SECONDS FOR THE ACTUATORS TO RECALIBRATE.
