Turbo power switch

[buicktom61]

Hi,

my GN has the digital Dashboard with the low and high pressure light for the Turbo.
When I start driving the low pressure light lights right after I push the the gas pedal a little bit. When I push it a more the high pressure light begins to light, but when I go the way to full throttle both lights goes off.
Is the Turbo pressure switch on the right inner Fender bad?

Thanks
Thomas

Or the wiring, or the boost hose.....

Take the switch out and plumb some REGULATED shop air into it and check the operation of the switch with an ohm meter.

That will determine if the switch is bad.

Great. Will try.
Thanks Thomas

I hope that's not your only boost gauge.

Yes it is, but have an extra new in a box. I am looking for the best place for it. On the A-pillar I have water temp and oil pressure.
