35psi is the correct pressure.

To reset the tire pressure monitor system, after correcting the problem, you have to use the options under the Driver Information Center (DIC) on your dash. The button you want to utilize is called the "set/reset" button, it is the third button from the left, directly in the middle of all the buttons. It has an arrow that points to the left. Press and hold the button until the DIC displays "Tire Inflation Has Been Set", this message confirms the tire pressure system has been reset. If, by chance, the DIC does not return to the standard display with the date, ect., you can press the "options" button to get back to the standard display. The "options" button is directly to the right of the "set/reset" button you just got done using. It has a lower case "i" on it.

Yes..there is either one inside your glove compartment or its on the floor near the drivers seat or located low on the dash..i hope this will help..Keith

Find and replace the headlight relay - its probably sticking relay contacts.

there used to be a magnetic setup thing the dealers used when i worked there give them a call and see what the dealer says they cant charge you for calling lol

There is a tool that you can buy or rent at the parts house that you can connect to a hand tool EG: 3/8 rachet to use with a tool to compress the caliper while you turn the rachet. You will see some raised teeth on the calliper piston for the tool to bite on. Since the rear brake is used to lock the parking brake it has to have a self adjust to compensate for the brake pad wear. EG: Old school drum brakes adjust when you back up depressing the brakes and letting off while the vehicle is rolling allows for the adjuster to reset the brake shoe clearance.

I had a similar problem, when turning to the right or on a right curve, the noise would go away. After some research I found it was the left wheel bearing assembly. I replaced it and the problem is gone. Therefore, check the wheel bearing assembly. You may have to replace it.

have the wheel speed sensors adjustment chk'd

sounds like an " OPEN " connection to the sender in the fuel tank, but where that open is, is the question. I would start by checking connectors under car to tank. Hope this helps

Yes, have your alternator tested. If it's putting out too much voltage, it could damage a lot of things in your electronics, as well as your battery.

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.  

yes i would just take it to a shop if you hook it up wrong or you touch two wires together you rist damaging the vehicles electrical system so i would just take to shop much cheaper then bying a new car, hope this helps and thanks for choosing fixya =)

You can buy these keys at www.ikeyless.com for $14.95 but it will need to be cut and learned. please rate

Have you tried to charge that battery? If you have and get the same result check your battery terminals for corrosion. If they are fine your battery may have failed.

There are three 10mm nuts holding the tail lamp assembly to the body.

no tcm its part of the pcm https://www.2carpros.com/questions/tcm-45767027

If you have the 3.8L First check the basics . Do you have spark ? Fuel Injector pulse ? My guess is that the ground connections under the coil assembly .are not tight . Very common problem that occurs during a water pump repair . Good luck

It is #3 in the picture. You should be able to get at it in the engine compartment.

With a monitor scan for the knock sensor defect or no signal from PCM should have around 5volts. Check Ignition key on engine off. With a piece of metal hit near the knock sensor and the voltage have to change normally. Also, the EGR valve not working or clog. For the hot engine Radiator cap defect or Electrical fan not working when hot. The radiator flush can be done if restrictions. hope it helps.

Check for a bad fuse
