To make the lights stop blinking and actually engage the transfer case you have to maintain the electric motor that engauges the transfer case. the contact points inside get worn and corroded and wont allow enough power through to rotate the servo. The motor is located on the transfer case and is held of by 3 bolts, remove and unplug. Any good 4-wheel drive shop can fix it for you for about $50 or you can take it apart and clean the contact points inside and relubricate it yourself in about 15 minutes. reinstall and your 4 wheel drive will stop flashing and actually work.

If the 4WD lights are blinking in a sequence, count the # of blinks between pauses. This is a message of the problem. On my 97 Ford Explorer, 5 blinks indicated a problem with the 4WD module. I replaced it myself and cured the problem.

their is an elctric 4wd module lcoted under your jimmy. if you do not occasionally use your 4wd, this motor will stick. if you listen under the truck while you try to put it in 4wd you might be able to here it clicking (tryin to switch). this problem is common in those vehicles because it is located under the truck were it it exposed to water, roadsalt, dirt ect. my guess is the part is about $200. if you can find it its rather easy to replace.

How do you fix a turn signal that stays lit but doesn't blink when lights are on?

Just replace the bulb. They stop blinking when the bulb goes bad. Usually if a bulb goes bad it will blink rapidly. If it stops blinking entirely or blinks only sometimes your flashing relay may have went out. It's a small box under the steering column usually.

You disconnected the batter to your 1999 Subaru Forester and now the hazard light will not stop blinking?

Under the hood of the car we found a yellow sticker with the following instructions and explanation for this "problem." To fix the blinking you need to locate a black button on the dash under the steering wheel. With the key in the ignition and in the on position press the black button to reset the system. The hazard lights should stop.
