You only need to change the tail light fuse if it is blown. If you haven't checked it already, do that. Those stop/tail bulbs are 2 filament bulbs. One filament is for brake lights, and other filament is for the tail lights. So it is possible to have brake lights and no tails, if the filaments for the tail lights are burned out. But of course, it is unlikely that all the tail lights would be out and all the brake lights still work. You may need a voltmeter to help solve the problem. It could be a problem in the headlight switch (a problem with the park light function), but is more likely a problem with the Lighting Control Module- or the Body Control Module-whichever your car is equipped with. GM first came out with the LCM, and a year or two later came out with the BCM. Both are mini-computers to control lighting and cabin functions. You would have to use a voltmeter and check things like power in and power out at the BCM of the park lights. You would thus need a wiring diagram to go along with the voltmeter. Those modules are located up under the dash-you can use google to see pictures of them, and maybe find locations.

Wheel bearing. A wheel bearing will make that noise when load is put on it. Changing the direction of travel could make it louder, or it could go away. Change the wheel bearings.

The horn micro relay is in underhood fuse box, number 21 in the circle. Your owners manual should have this info. If you don't have an owners manual, you can look at one for free, my.gm.com It'll ask for year--make model. The relay might not be the problem?

Take it back to the installer.

Hello Vason, Is your engine light on? If so, you need to plug in a diagnostic OBD II reader. Acquire the codes and follow their designation to determine the probable fault source. And yes if any monitored system, for any reason, does not complete its start up cycle your vehicles ECC will not provide the green light all is well return to the diagnostic tester.

The a.i.r. Pump that injects air into your exhaust , that is driven by the accessorie belt does not push enough so there is a secondary electric a.i.r pump that pushes the extra air needed to burn off the emissions in the catalytic converter if the secondary pump is not working properly it will not pass because the convertors are not getting the extra air needed to do there job.

Tom, Yes, you should check all evap hoses for cracks and leaks. Common Problems That Trigger the P0442 Code

• Defective or damaged fuel cap
• Distorted or damaged Fuel Tank Filler Neck
• Small tear or puncture in the Evaporative system hose(s) and/or Carbon Canister
• Defective Fuel Tank Sending Unit gasket or seal
• Small split in a seam of the Carbon Canister
• Defective Evaporative Vent Valve and/or Evaporative Purge Valve
• Defective or damaged Fuel Tank
• Defective Fuel Tank Pressure Sensor
• Defective Leak Detection Pump
• Slightly loose and/or worn clamps or hardened O-rings anywhere in the EVAP system Check the attached links, "I hope this helped you out, if so let me know by pressing the helpful button. Check out some of my other posts if you need more tips and info."

first place to look is at the wheel sensors and wires at those points then run the fault codes to see if there is an issue with the abs control module

Hi there I am technology tech mechanic I work on electric and man. I come from long line of mechanics I am 5gen!!!!! No it is emc system I am betting that the heated o2 is not doing it job test them to see! It would also have to do with the obd codes for the future the obd codes just tell you bout were to start or what is the bigger problem with the system! Bench test the o2!!!!! Have you check the mass flow sin. Check out the injects they may be taking air you can just test with a spay bottle and leave car at idle and spay them make sure you are not putting to much but if you see it take in water and you can hear from the motor too!!!! Also do the manifold and all vac lines and pump and if the is you will see and hear it here is my email address let me know what you find out and if you need anything else or need steps to test ill give you my phone number if need be so that you can get the car fix! God bless you and good luck hope that I hoped you out but for real let me know what happen

Sounds like a problem with the key switch.

HVAC Compressor Controls Circuit Description The operation of the A/C compressor clutch is controlled by the body control module (BCM) and powertrain control module (PCM). The BCM receives an a/c request signal from the heater a/c control assembly through circuit 66. The BCM then sends a class 2 serial data message to the PCM through circuit 1807. Power for the a/c compressor clutch relay is supplied by the A/C BFC fuse and circuit 439. When the PCM receives an a/c request message from the BCM, the PCM grounds circuit 459 allowing the a/c compressor clutch relay to engage. Ground for the a/c compressor clutch is supplied through circuit 450. Do you know what a class 2 serial data message is ? Class 2 data is a high speed data transmission. In order to control serial data line traffic, class 2 uses the peer to peer method along with message arbitration in order to manage the data line traffic. The class 2 data line includes the following control modules: ?€¢ The body control module (BCM)

?€¢ The electronic brake control module (EBCM)

?€¢ The powertrain control module (PCM)

?€¢ The sensing and diagnostic module (SDM)

You need a factory scan tool to diagnosis , it's the only way to see if transmission is sent an received ! The intake air temperature (IAT) sensor is a thermistor which measures the temperature of the air entering the engine. The Powertrain Control Module (PCM) applies 5.0 volts through a pull up resistor. When the intake air is cold, the sensor resistance is high and the PCM will monitor a high signal voltage on the IAT sensor signal circuit. As the intake air warm, the sensor resistance becomes lower causing the PCM to monitor a lower voltage. If the PCM detects an excessively high IAT sensor signal voltage (low temperature indicated), DTC P0113 will set. Test the signal circuit of the IAT sensor for a short to voltage.

It goes to 2 or 3 places to grease transmissions sets: to gear, to differentials.
