If your mobility scooter is experiencing difficulties and not running properly it might be due to a more serious issue. Only an expert can find the true cause of technical issues. Avoid trying to diagnose the cause of the issue yourself. This often leads users to attempt to fix something that doesn't need fixing. It also may make the initial situation worse and more expensive to fix in the long run. Any issues that aren't obvious or easy to fix should be handled by a professional scooter repair technician.
Hummer H2 4wd service light comes on when I start the H2
If the 4WD service light comes on when you start your Hummer H2, it could indicate a problem with the four-wheel drive system. This warning light could indicate a problem with the transfer case, the drive shaft, the front or rear differential, or other components of the 4WD system.
It is recommended to take your vehicle to a certified mechanic or a Hummer dealership for proper diagnosis and repair. The service light coming on could be a sign of a serious problem, and it is important to address it promptly to avoid further damage to your vehicle and ensure safe operation.

2003 HUMMER H2 FUEL GAGE READS EMPTY ONLY
You replaced the fuel gauge stepper motor two times ? Did you do it correctly ?
Fuel Gage
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:
• The PCM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.
Reviewing the fuel system description will further explain how the system functions. Refer to Fuel System Description .
Did you try replacing the fuel level sensor ? Check for DTC'S diagnostic trouble codes ?
2007 Hummer H3. Does anyone have a step by step guide for the expansion valve replacement?
no need to unless the compressor blew up.
why not ask a shop to fix it.???
they do a battery of tests and fix it fast. even in hours.
to replace that valve behind the evaporator core on most cars is horror. (nothing less)<< so why we do all tests first not 10 hours labor for zero gained. that be over the top.
THAT act BREAKS OPEN THE LOOP .! best is avoid that.
AND ALL R134A Refrigerant is lost. doing that.
a real shop captures it and looks for metal particles there.
but this a last step. not first and testing is first.
.lots of tests are first.
low-side pressure (30 psi par)
high-side. pressure (300 psi par)
are dampers stuck closed
fuse blow
bad compressor clutch
make sure compressor is ok, first, if is the expansion valve is ok
but there are test just for that.
Dye tests for leaks to be found .
once you break the loop and pump down vacuum pump is manitory
to remove all water there (like 85% humid air ) and if is R134 hates that. and fails,.hard. (weak AC)
and once loop breaks, a new receiver/dryer is need too.
and more, lots more.
How do I know if my 4x4 buttons on my dash indicators are bad? Or why isnt it turn on?
Unless you have the Adventure Package, you don't have it. You need an auto electrician to tell you what you have and if the buttons are faulty.
If you are on 4 Low, is your top speed 20mph? If you can do 70mph in that hunk-a-junk, you are in High.
Find a dirt road and get some friends to watch . If you boot it, do all the wheels spin, or just one pair?
Those are the easy ways to check.
