Check all your connections first. you really need to make sure they're good. this issue is not for a rookie because it can come down to a defective PCM... But if you are willing to try and fix it right then

2005 chevy cobalt electric power steering issues. "power steering" lights up on the dash, and the transmission shifts hard, engine lacks power.

Sounds like either the TCM (Trans control module) OR the plug from the TCM going into the CAN Bus. Check out the Youtube video for checking the CAN resistance... might save you big bucks! http://www.youtube.com/watch?v=7MJw7Nj3J7k&feature=youtu.be

2000 chevy blazer 4wd stumble stall on start and idle

Its not The mechanics fault all the time, you may fix something then something else goes wrong thats mechanics 101. I've had this problem before I replaced my ignition coil and my fuel pump, fixed it right up in my 96 f150. Give it a try its a whole lot cheaper than most options.

We have a zenith dehumidifier model ZD300 & the bucket full light keeps flashing. the percentage number wont go higher than 1%. we have turned it off/on & unplugged it. When we do this it will...

I've had the same issue with mine. I am a 12 year refrigeration tech. I checked the float switch which would normally cause that indication light. However manually pushing the switch and then checking it with an electric meter that was not the case. I think that is instead, an error code set by the manufacturer to assist the service tech when or if this failure occurs during the warrenty period. I also checked the next possible failure in the sequence of opperation which would be the compressor overload relay. That is sometimes why, as some people have posted, that after when unplugging the unit, it operates for a short time then again fails. In my case that was the failure. If that would have not been it than I would have tried the compressor start relay. I purchased the overload relay from my local HVAC/plumbing supply for around 7$. The control can easily be replaced by any handy homeowner. Also, as a service tech, 7$ and two wire nuts is better than a 145+$ service call.

Status light is red, why? I have a Roomba Discovery.

Hi.

If the red light is solid, that means that the Roomba is near to full discharge. If the light is flashing red, then the Roomba is completely out of charge.

If the Roomba is fully charged, then there may be a fault.

Here full list of light codes:

Pulsing Amber - Charging
Green - Fully Charged
Amber - Partially Discharged
Red - Almost Fully Discharged
Flashing Red - Fully Discharged"

Here manual

How to reset service reminder after i changed oil and filter after a week the engine light came on and derated the engine power

That is not a service reminder. The light comes on when there is an emission/engine control related problem, either with a sensor or engine management component. Go to a car parts store that does free testing (like Napa, Auto Zone, Kragen/O'Reilly's, etc.) and have the code scanned. From there, you will be able to research the code online or come back and ask what could be causing the problem here.

Roomba red 4100 cleans in small circle stops starts agains cleans small circle stops then status light comes on and clean button blinks.

When the status light comes on, the Roomba is going to sing "uh-oh," and then beep a number of times. Count the beeps. They're a code that tells you what's wrong with the Roomba. You can check iRobot's website for a chart of beep codes. Search "What is Roomba saying to me?" on the troubleshooting page.
