if there was no collision and the air bag light is on there is a code set in the module that needs to be pulled then checked out. with the light on you have no air bag operation. the module can only be reset if the problem is corrected and the use of a scan tool is used to reset module.

check all fuses and if that isn't it then tap into another power source of the same amperage rating

under the dash to the left of the steering colume usually near the fuse panel. turn on the hazard lights and look for the relay that is clicking this will show you what the signal flasher looks like. then look for the other flasher. have found some attached to the top side of the colume.

Have AC drained, remove serp belt, jack up car and remove lower front access panels, unplug wiring , remove 13or 15mm bolt from manifold lines on back of compressor,remove the 4 mounting bolts.

The 171 is an oxygen sensor code, you can look up That alone is not the reason for stalling or idle issues

What you will need is a replacement Window Regulator. You should be able to find one online for around $50.00. Make sure you Order the correct one. Drivers Side Front..... Passenger Side Rear... Each would be different. Removing the inner door panel. Check for videos on Youtube for your model and year to watch step by step instructions. On a scale of 1 to 5 this would be 3 to replace. Removing the regulator and getting the new one into place can be tricky. Just take your time and pay attention to how you remove the old one and what bolts and screws go where.

Run your Vin # at the dealer-- to see how it was built

some blink all the time as a theft deterrent but some blink to tell you that it is activated only..

It sounds to me that your belt or tensioner is worn, if the noise goes away when the ac is off then it is just the belt slipping, it takes a lot of power to run the compressor and if the belt is worn it most likely slipping on the pully when you engage the clutch.

When we detect a lean mixture code from our vehicles, our first reaction may be to replace the oxygen sensor. However, testing oxygen sensors before replacing them is a good idea. The best way to check the operation of the sensor is to run a simple test. And all you need is a voltmeter. A voltmeter is usually cheaper than car diagnostic tools and is available within 100 eurs. Here I will use an original Autel PowerScan PS100 for 56 eurs from EOBD2.FR. How to check if your oxygen sensor is bad and needs to be replaced: Step 1. Find the oxygen sensor sensing wire, connect Autel PS100 to the feedback wire and ground and then choose the mili volt operation. Step 2. Turn on the ignition key to start the vehicle and run the engine at idle to warm it up. Watch data on PS100. The voltage should move slightly at whatever voltage the sensor is centered at. Step 3. When you pull the oxygen sensor data stream up, the output voltage from the sensors should constantly bounce between high and low with the meter dropping and rising, as the engine is running in closed loop. The volt meter should stabilize at the original operating voltage when the engine returns to idle. If your oxygen sensor does not show the above reactions, it is probably that it is bad. Note: If the error code shows a malfunction exists with related components such as an engine misfire or other engine problems, please do not perform this test.

when engine get warm oil get thinner so it can leak from a small hole belt will make noise on dry pulley change belt

A flashing check or service engine light indicates a misfire thatr is happenning at that time. Severe misfires can quickly harm your catayitic converter, and need to be corrected quickly, hence the flashing light. Could be ignition, fuel injection, mechanical, or any number of other things, but check it as soon as possible.

You need a window regulator.

NO -should be hub bearing assembly

stuck flap under dash.

No. The switch provides current over two wires directly to the motor. The switch also reverses polarity internally to move the window in the opposite direction. If your motor wont turn, use a meter to check for voltage. My switch went bad and would only roll the window down and not up. Had to buy a whole new switch.
