Hello. I've had my first Toyota, 2000 4Runner Limited, for two weeks. We love it. However, the 4x4 indicator light on the dash is constantly flashing. It only stops momentarily when I push in the 4 wheel drive button, but then it continues to flash. I already replaced the Transfer Indicator Switch, but it didn't solve the problem. Any suggestions? Thank you!

 

Check all the vacuum lines that engage the 4wd.

 

Thank you so much! You were right! I just had a hole in the vacuum hose! I am also having another problem with vibration, could you possibly lend a hand with this?: https://www.yotatech.com/forums/f123...speeds-192609/
