My doors autolock by themselves while im driving,continuously? what is it that?

it has not worked since ive had the car. I used to have heat but now it doesnt even blow out.

you can feel heat coming from vents when driving but it wont blow out


my wife went to leave for work today, she tried starting the car all it did at first was cranking and cranking then she turned off the key and tried to re-start the car then it started once it did start it was running rough check engine light came on and was flashing , it acts as if it has no compression but runs rough it seems to have no compression, im afraid to try driving the car anywhere to get checked out

I have a car that I haven't driven in about 10 months. When I went to drive the car it would power on (new battery), but would not start. It was driving before this time. I had triple A come out and test everything. The guy said it might be the fuel pump. I had it towed to a local mechanic. The triple A guy wrote on the slip that it may be fuel pump problems. Mechanic says it is. Do fuel pumps go from sitting? When I was driving the car before this it was driving fine and was not making any sounds at all. Just don't want to spend 655.00 if it may be something else.

My car makes a very loud screeching noise only in reverse all the time, brakes applied or not. I have checked the rotors and they seem fine. This is getting very irritating and would like to find the problem so I can fix it!

Thank you, Brett

There is full power under the hood. The head lights have power at the plugs but the interior switch will not turn the on.

Very small amount of antifreeze leaks from crack when car runs, then stops when is turned off. Car has never overheated.

The emission light has been on for a while, then one day, was at highway speed, slowed to 35 mph an would not go faster.

Was driving home and all of a sudden, 35 was top speed.

I need to replace my spark plugs(100300 miles) on them my owners manual says replace every 1000,000 miles. There is a lot of plastic covering the area where they reside.That's why I'm asking what do I need to remove to gain access!
