Buick Repair Questions? Ask a Mechanic for Answers ASAP
can you tell me the year and make and model of this vehicle ?
do both fans run full speed ?
with the key OFF they shut off ?
if so are you sure there are no codes set in the computer ?
any access to a scan tool to see live computer data ?
ok do you know if the code for the tempo sensor reset ?
the coolant sensor was 2 wires you replaced one yellow and one black correct ?
with the key ON with the fans running if you unplug the coolant sensor will the fans still run ?
ok can you see if the yellow wire terminal shows 5 volts at it at the connector you unplugged with the key ON
ok check to see if it reads 5 volts with the key ON
yes just reply right back through this post
that wire should show 5 volts at it with the key ON either that wires i bad or where the wire is crimped inside the connector to the terminal is bad
its very rare for a bad computer to cause this problem
the other end goes right to the computer
ok let me know
that is correct
