160 is a common temperature for a thermostat but the sticking is a problem.
I assume this is an analog gauge? Is there no movement at all?
If there isn't, then the gauge itself has failed and will require replacement. It's rare that these primative gauges fail but it can happen.

My check engine light is on, and today my temperature gauge stopped working and we have replaced the engine coolant sensor and the connector and temperature gauge still not working. PLEASE HELP


Could be the thermostat. I know nothing about cars but I noticed my 2000 Grand Prix temp gauge was not going to the normal level. My wife drives this car so I didn't notice it for a month or so. Eventually the Engine light came on. Took it to Autozone and the code came back as P0180... (1) low coolant (2) bad thermostat (3) enginge fuel temp sensor. They used a code reader that was about the size of an Ipod nano.

Coolant was okay, so took it to my mechanic. His netbook sized computer showed it was the Thermostat. He reset the codes and the temp guage went back to normal. Was short on $40 for the fix at the time, so I parked the car and promised to bring it back in 3 days. Went out and checked the car a day later at 25 degrees outside without starting the car... gauge still sitting at the normal level. No question it's the thermostat. That car will not be driven again until T.stat is fixed in 2 days.

Where is the fuel pump resistor on a 1999 gtp?


It is in the fuse panel mounted under the hood near the overflow coolant bottle.
It is a square shaped device that is actually a relay, labeled with the number 2866.

The sensor is located near the hood latch area in front of the radiator. If the temp is reading incorrectly, chances are it is defective. You can purchase a new one, they relativly inexpensive.
Disconnect the electrical connector then remove the sensor.
Good luck, let me know.

A/C issue with 99 Grand Prix


Check the ac filter, it might be dirty and thats why it is not blowing out enought cold air. The filter is located under the wiper cover but behind the firewall on the passengers side. You access this by lifting the hood and removing the rubber type gasket that holds both together, right on top of the blower unit.
