Jump Start the Tach and Speed Needle
I don't know if this is just mine or if it will work for other people. As alot of people know the tach and speed odom. needles stick until the car warms up for some people who on the 1st gen lexus. Well by chance I found a way to jump start them. (on my car anyway). Since the root of the problem is that the contacts are going bad, I found that turning the dash light all the way off and then back on that this will give an extra electrical boost to the contacts and the needles will start working right away. Doing this you don't have to wait for the car to warm up before they start working.
Like I said may just be my car but has worked for the last few times my needles have been stuck at crank up. So I thought I would share the info and see if it works for anyone else.
