Oil pressure gauge stuck on 80psi. Is it the sensor?

thanks for that. My other problem is the fan switch inside only blows when it is on 5. Lower numbers 1 2 3 4 hardly blow at all. Is this the resistor?

Well I would say that your problem blows but it doesn't so it's a problem. Sorry for the bad humor but I would venture to say that the blower motor resistor is bad. It's a cheap part if it's manual control but kind of pricey if it's auto temp control.

Thanks for the help. Kinda figured that it was resistor.. watched a video of replacing it. Doesn't look to complicated. Again thank you.. Ingrid

I'd like to give my 2 cents on the sending unit. DON'T buy OEM! In most cases, OEM stuff is as good, or better than, aftermarket stuff. That said, I have owned my 2000 Vert for almost 18 years. So I've been thru my share of sending units. I've even had them fail showing ZERO pressure! I've never had a factory sender go more than 3 years, tops. They either read high, low, or start leaking. GM needs to seriously consider sourcing a different manufacturer for oil sending units. Buy a real good aftermarket sender from NAPA, or other good Auto Parts Store. I finally went with an El cheapo aftermarket sender 4 years ago. Still works fine, doesn't leak, and has lasted longer than any OEM unit I've had, so far. Bought it at O'Reilly's. Hope this helps
