usually in the middle of the dash way back where you have to remove dash to get to it .

Depending on year some had a fuse panel on the end of instrument panel on driver side. Check fuse for 4 wheel dr. Sometimes backing up will help.

A educated guess I would have to say there is a problem with HVAC control module ! electronics you know ! But that's not the way to do things ! There could be codes stored in the module. The Chevy dealer my have a reflash bulletin for this problem . Then can reflash , reprogram the control module ! The first place to start is checking for codes in the HVAC module.
The HVAC control module is a class 2 device that interfaces between the operator and the HVAC system to maintain air temperature and distribution settings. The battery positive voltage circuit provides power that the control module uses for keep alive memory (KAM). If the battery positive voltage circuit loses power, all HVAC DTCs and settings will be erased from KAM. The body control module (BCM), which is the vehicle mode master, provides a device on signal.
Air Temperature Sensors The air temperature sensors are a 2-wire negative temperature co-efficient thermistor. The vehicle uses the following air temperature sensors:
?€¢
Ambient Air Temperature Sensor

?€¢
Inside Air Temperature Sensor Assembly

?€¢
Inside Air Temperature Sensor Assembly-Auxiliary

?€¢
Upper Left Air Temperature Sensor

?€¢
Upper Right Air Temperature Sensor

?€¢
Lower Left Air Temperature Sensor

?€¢
Lower Right Air Temperature Sensor

?€¢
Upper Air Temperature Sensor-Auxiliary

?€¢
Lower Air Temperature Sensor-Auxiliary
A signal and low reference circuit enables the sensor to operate. As the air temperature surrounding the sensor increases, the sensor resistance decreases. The sensor signal voltage decreases as the resistance decreases. The sensor operates within a temperature range between -40?° to +101?°C (-40?° to +215?°F). The sensor signal varies between 0-5 volts.
The input of the duct air temperature sensors are different from the ambient and inside air temperature sensors. The HVAC control module converts the signal to a range between 0-255 counts. As the air temperature increases the count value will decrease.
If the HVAC control module or auxiliary HVAC control module detects a malfunctioning sensor, then the control module software will use a defaulted air temperature value. The default value for the ambient and inside air temperature sensors will be displayed on the scan tool. The default value for the duct air temperature sensors will not be displayed on the scan tool. The scan tool parameter for the duct air temperature sensors are the actual state of the signal circuit. The default action ensures that the HVAC system can adjust the inside air temperature near the desired temperature until the condition is corrected.
The ambient air temperature sensor mounts underhood and can be affected by city traffic, by idling, and by restarting a hot engine. Therefore, the HVAC control module filters the value of the ambient air temperature sensor for temperature display. The ambient air temperature value is updated under the following conditions: Or you can just buy a new control module an hope that it fixes it. $89.00 at www.partsgeek.com

if its a 1500 4x4 just pound on it a lot with hammer

id find blower motor and hit it with a hammer if it turn on its bad also look at the wire to the resistor they melt down if its bad put new connector and resistor in iv done a few

top up your power steering ,fluid may be low.

Check the interior fuse panel, there are an additional 20+ fuses, usually on the end caps of the dashboard.

2005 Chevrolet... | Answered on Mar 03, 2015


Yes there is something in common . Check the fuse # 79 10amp in the underhood fuse box . For O2 sensor , heater power .
The PCM commands the heater ON or OFF to maintain a specific HO2S operating temperature range. The PCM monitors the voltage on the HO2S heater low control circuit for heater fault diagnosis. If the PCM detects that the HO2S heater low control circuit voltage is not within a specified range, DTC P0030 sets for HO2S 1, or DTC P0036 sets for HO2S 2.
So this is not in spec. an it set the other codes !
If the PCM detects that the heater current or the heater calculated resistance is not within an expected range, DTC P0135 sets for HO2S 1
If the PCM detects that the heater current or the heater calculated resistance is not within an expected range, DTC P0141 sets for HO2S 2.

I would have the fuel pump and or line checked out. Usually with these trucks, it is a malfunction within the fuel system.

Here anything airconditioning is considered rather specialist as the gases used are environmentally unfriendly and only suitably qualified people are allowed to commercially handle those gases.

Changing a condenser involves de-gassing and re-gassing the system and any gas in the system should be recovered and stored and there are heavy fines for those caught releasing gas into the atmosphere, though once de-gassed, theoretically anyone could carry out the work though it would be unwise for a person without experience and access to repair instructions.

Take the wheel off and check the brake pads, they are probably worn down, and the metal backing on the disc brake pad is rubbing against the rotor.If that is the case, the rotor will need to be replaced, or turned down if it isn't too bad.

bad connection on oil pressure sensor, they just go bad

2005 Chevrolet... | Answered on Feb 03, 2015


check fuel pump and filter. even thou you may hear it run, they need high pressure. also check if you have spark. they sell little hand held pen looking items that you just put against the wire and it will tell you if you are getting spark.

it is located under dash on passenger side right next to the blower motor
