the only way you can retrieve these codes is with a code reader. it's cheaper than a scan tool. problem with these is it only reads the codes and the booklet tells you what the code means but it can't clear the code and it can't change the parameters to keep the codes from coming back. do me a favor and rate this ...thanks

Might be the thermostat. Check it

sounds like you either have a bad fan motor or else the thermostat is sticking. I assume you checked the radiator and it is filled with antifreeze.

Bad grounds. Check the main three. Battery to engine, battery to body and engine to body. Can't find one. Put one on.

Your anti theft light is it on your using your regular key not a valet key sound like your alarm system

I'm assuming you mean your key wont turn in the ignition. first off check to make sure the car is in park. then what you gotta do is put in the key and put a little pressure as if turning but dont turn too hard, then even though the steering wheel is locked you will have to try to move it a little, if you parked with your tires turned then you will want to try to turn the wheel in the same direction, (even locked you should be able to move it about a half inch) you will have to turn the wheel hard but it should move enough to allow the key to turn, you may have to jiggle the key a little in the ignition but it should eventually turn, just remember not to try turning the key too hard, the extra force wont make it go but can cause the key to break. this tends to happen when you turn the car off andthe steering wheel gets locked if the wheels are turned hard in either direction. also if multiple attempts at this still dont work, try taking the key out and turning it over and trying again. Even though both sides of the key are identicle, because of wear on the key and the ignition, sometimes when the wheel locks the ignition, it will only turn if the key is put in a certain way. Hope this helps, good luck

First I'd check your water levels and top up if required. Then check for leaks. If all is good so far I'd look at your water pump to make sure water is circulating. So check the belts for the correct tension and check the pump for any leaks coming from it. Leaks can be a sign of a worn pump. Check the thermostat next to see if it opens at the correct temperature or remove it altogether. Hope this helps. Just don't drive to much on an overheating car as the can warp the cylinder head which is a much more expensive issue to put right.

need new coil pak often can get one at salvage yard about 25 dollars

worn ignition key cylinder eventually itll keep getting worse and lock u out from starting for 9 minutes have to replace ignition lock cylinder

Make sure there is no air trapped in the cooling system by bleeding the system.

You need to bleed the air from the cooling system. The bleeder valve is located just behind the water pump housing. It is a small hex head (7MM) screwed into the coolant bypass tube. Pour coolant into radiator with the valve opened until coolant comes out of the valve. The cooling fans will not come on until the temperature reaches 225 degrees.

I usually pull up to my garage back wall, properly inflate my tires and use the wall as a guide and adjust the low beams to a height of no more than 40 inches.

Can you simply purchase a belt for the non-a/c version of your vehicle and eliminate the pulley completely??

Sounds like a broken wire on the - side.

Do you know where the Instrument panel fuse block is ? Open the right front door, end of the I/P or dash. End panel comes off . just grab an pull. Fuses under panel and are marked on inside of panel. There are four fuses. Cluster /Batt 10 amp fuse , PCM/PASSKEY/ CLUSTER 10amp , IGN1 10amp , and MALL/CLUSTER 10amp fuse .

is the battery low? this sometimes happens as a low voltage warning, disconnect the battery charge it and reconnect, double check the alternator, to make sure its the right one, if that does not work,

You have to make sure you have the right relays and also the coolant sensor that runs the fans might be grounded. You would have to check with a ohm meter or a conduit tester, good luck.

Check door switches to be sure they spring back.

Take your father down to the local pub and leave him there then take the car to an accredited auto electrician to have it fixed NO honestly this is the best idea as it will cost less eventually to have it fixed professionally
