If you look at the top of the head light assembly with the hood open just past the top rubber seal, you will see an alan head adjustor screw. This will adjust the low beam light up and down. the high beams are fixed. I would suggest shining your headlights on to a wall or garage door to get them to the same hight you need.

I am assuming that the design was not changed from my 2005 updander to your 2008. I had to adjust mine while on a road trip. We had a lot of people and stuff in my vehicle which made the headlights shine higher than normal. I was getting a lot of on commig traffic flashing. I was able to ajust them down fairly easy with those adjustor screws. Hope this helps.

Did you note if other times the lights went off? Some devices keep the little leds on all the time when the car is used! let me know and in the same time i will reserch it on the manual!bye

Check out this case study on a Chevy Impala for that P1404 code on a new EGR. I only watch the beginning, (too long for me to sit and watch) but seems to be a communication issue. https://www.youtube.com/watch?v=HT4OnP4U0to https://www.google.com/search?q=P1404 https://www.google.com/search?q=P0404 ..

Question edited for clarity and all the typos. Question moved to sub category. Did you disconnect the battery recently? It could be many things, but it could be the security system immobilizer. You should also check for fault codes. When you say 'nothing works inside', do you mean things like the dome light, the radio, and the dash lights? If that is the case, you need a mobile auto electrician. https://www.google.com/search?q=2005+chevy+uplander+security+reset ..

Question edited for clarity. Question moved to sun-category. You have modules issues. For that you need an auto-electrician with a pro grade scan tool computer. They collect data from each module and tell which are causing the issue. Likely to be ECM and BCM issues.

this is the security system light flashing to let you know it is active

First check the fuse and the connection under the seat. If these are both ok disconnect the heater connection under the seat and use a multimeter to see if the heating element is operational.

Note the diagram for mil/malfunction indicator lamp. Wiring connector at instrument cluster, it appears pin 4, brown wire with white tracer, in my opinion that wire is ground controlled by the pcm, depending on the situation. The lamp needs voltage and ground, if the lamp itself is ok. good luck

Generic obd 2 system allows access only to systems that affect exhaust emissions and dealer level software is needed for everything else. A fault that affects the exhaust emissions should switch on the engine check light and store a fault code in the memory. While the light is on the engine is operating on the get-you-home programme. When there is a problem, after a thorough visual inspection and ensuring the routine maintenance is up to date, a code reader or scanner is used to read stored fault codes, examine live data and suchlike. The fault code is an invaluable start point in the diagnostic process and repair, but in order to advise you further you need to tell us what the code is...

Hmm I don't know what the skreeting sound might be, but your lack of power and spuddering is most likely do to an ignition problem. This van has a V6 and GM V6's use a waste spark system. Many times a spudder or lack of power is due to a failed ignition control module or coil pack. If you have a failed coil pack you should replace the ignition control module as well because it most likely has damaged the ignition control module anyway.

suspect a problem with fuel system , like the filter needs replaced perhaps

The transmission speed sensors of normal cars are located near the front and rear of the transmission housing. Check the repair manual for your car. I hope it will help you out.

When the temp. gauge pegs hot what was the real temp of the engine ? Hook up a scan tool that can view live data to see what temp. sensor is reporting to the PCM / ECM , use a Infrared Thermometer to test temp at the engine . GM had instrument cluster gauge problems , bad stepper motors that control gauges . I replaced bunchesof these because people thought vehicle was overheating . 2003 to 2006 gm vehicles .

Will be located near the wheel hub. As long as there is no physical damage I would guess you will be replacing the sensor

Sounds like a faulty wire set; also possible the wring is improperly installed and the end connectors are not making proper contact with the plugs/control module.

There may be an access hole plug at the bottom of the trim panel you can remove to insert a flat bladed screwdriver into the latch tommanually release it. If no plug there may be an intention in this area where you can drill a hole into the trim panel to insert a screwdriver. Then you can purchase a plug from a Chevy dealership to cover it up.

While there are a variety of reasons your Chevrolet Uplander is overheating, the most common 3 are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat. A more uncommon reason is your radiator is partially scaled up and under a heavier load, the cooling capacity is not sufficient.
