Random blinking of the learn light is normal.

To have your lights come on automatically when you walk into an open garage, you must START with the lights ON. If you don't want that feature and you want to turn it off, you must START with the lights OFF.

To turn the feature on, turn the lights on manually with the wall switch, then press and hold the LIGHT button for about 10 seconds until the motor unit light bulbs flash. Now, if the light bulbs are on, manually turn them out and then walk out through the open door. The light bulbs should come on.

To disable this feature, start with the light bulbs OFF and everything else is the same.

This indicates a thread break, but if thread is not broken I would rethread the top as there is a thread break sensor on the take up spring that could have been missed in threading. If that does not solve then I would have a look at take up spring and attached sensor

Hold light blinking, check engine light on, engine slows down


check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.

ABS light is on and Track-Off light is blinking


"ABS light came on and Track-off light started blinking"
This happened after I replaced the rear struts (shock absorbers") It turned out to be the left rear wheel sensor ($156.75). I must have damaged it when I replaced the strut. The way to check the 'rear' sensors is to remove the back seat to gain access to each sensor plug (2 prongs). Unplug it and check for continuity. If there is no continuity then you have a bad sensor, or an unlikely break in one of the wires. I checked for a break in each wire but they were fine.

Anti-lock brakes come on just before I stop when payment is dry


did you check the alb sensor? You might also have the "return spring" stuck in the emergency brakes. Sometimes they break causing the brake to lock, which in turn activates the alb. Also, check the brake oil level, in some cars alb dont work properely if the oil level is too low. Good Luck

Motor moves 5 in" and reverses and light blinks 5 times


In the manual it says if you can hold the wall button down & door closes. You have a short in the wiring to the reciever eye. Try substituting some new bell wire in its place, or test the wires for continuity.

Sensor


There are spring tabs on the inboard side(engine side) of the reservior that are part of the sensor and you have to squeeze together in order to slide the sensor out. The springs run up and down as compared to the master cylinder. Good Luck

Intermitten remote sensor issue


Evidently 2 good remotes point at the problem being the remote sensor on the TV itself. I have about 4 remotes I can adjust volume w/ including the remote that came w/ my samsung. The TV exhibits the same behavior w/ all of them.

Per the samsung site, the "test" for this (remote vs sensor) is to us a digital camera, (including the kind that's on most cell phones) to "see" if the remote lights up. Just point it at the camera/phone, and press any button. You should see a bright flashing light on the camera/phone's LCD screen. If not, REJOICE! All you need to replace is the remote or batteries in it. If you do see the light, good luck if you're not in warranty. I've been unable to find any procedures for replacing this kind of item.
