sounds like you have a leak concern if they are adding freon

however, it also sounds like a restriction in the system and/or a defective TXV

do you have pressure gauges... this is the only way to diagnose an a/c system without just throwing parts at the concern

TAKE IT INTO AUTO ZONE PARTS STORE, THEY WILL SCAN IT FOR FREE AND GIVE YOU A PRINT OUT OF THE COMPONENTS THAT ARE BAD AND ALSO GIVE YOU AN IDEA OF HOW MUCH THE PARTS COST AND THE PARTS AVAILABILITY....SORRY ABOUT THE CAPS.

Check battery voltage, battery connector cleanliness, and correct any problems such as dirty connections.

Check the amperage draw of the starter. 75 to 110 A should be plenty for a rapidly spinning starter. If it doesn't spin rapidly with this amount of draw on the thick cables coming off of the battery, then there is something wrong with the starter.

If there is no or little amperage draw, and the starter doesn't turn the engine over, then there is still something wrong with the starter, more specifically the solenoid which sits on the starter.

Good luck on this repair.

My car had the same problem. Turns out the gear shift was not correctly going into Park. My mechanic adjusted the gear shift and now it's fine.

Whats is with this question tonight ... ... the simple answer to the water pump replacement is you repoace it when it starts leaking ... the pump itself is nearly bullet proof. It is the seal that is the weak part ... when it starts leaking ... replace the pump.

You have to take the dashboard completely off. I just had air conditioner work done and they had to take the dashboard off so I had them change EVERY light in the car. I have a 2000 S70.

Have the throttle positioning sensor checked for that sounds like the problem you are having with yours

Locate the power steering unit on the Engine and you will see a reservoir attached to it. Add fluid there.

This is almost always because a rod and clip have come apart.The rods that go from the handles to the mechanism are just under ¼" thick, and hve the last maybe 3/8" bent over at a 90º angle. That bent over part then goes through a hole in the mechanism for the rod to do its job. There is a plastic clip in the hole, which the rod end is pushed into. Then a little part off to the side of the plastic clip is clipped over the rod to hold the rod end in the hole.

When those clips get hard with age, they fracture, let go of the rod, and then the rod falls out of the hole in the mechanism.

The rods from the outside handle to the mechanism are pretty short, and are hard to see. They are rather hidden by the mechanism itself.

Make sure the window is up so the glass doesn’t get in the way. You might need a dental mirror to see what’s going on. (They sell that type of thing, but bigger than what the dentist puts in your mouth, at auto parts stores.) You might be able to get a good look with a hand-held mirror.

If you need a flashlight, put the flashlight by your ear, and point it at the mirror to bounce the light off the mirror to what it is that you are trying to see. Once you have seen what you need to do, you will probably need to do the actual repair by sense of touch.

Don't do this on grass. If you are trying to install the clip and you drop it, it can hide really well in grass.

There have been a lot of problems with the compressor cutting out when it gets hot. When the A/C begins to blow warm, check the power supply wire to the compressor. If there is power in the wire, you will most likely have to replace the compressor. If there is no power, you will have to trace it back to see what the problem is (a wiring diagram will help greatly).

Get checked the AC pressure. Check by pressing the the AC valve. Turn on the AC and check if the compressor is working. also get the blower fan checked. If all checked ok.Then the problem can be with A/C module. The a/c module which is housed inside the main computer box . Check out.Thanks.
