Have an AC repair shop hook up a set of AC pressure gauges while this is happening to see what is going on. You could have a defective AC compressor or a low refrigerant charge in the system. And as to the hot weather causing it to act up that would be normal, the AC would cool fine the cooler the outside air is, problems like worn out compressors and low system refrigerant charge levels would only show there ugly head in hot weather conditions. Also make sure the cooling fans fo rthe AC and engine are working properly. Good luck with this.

You'll have to be able to duplicate the problem to find it.
If it will quit working after idleing for a period of time, a mechanic would check for voltage to the compressor at the relay and the compressor clutch, then go from there.

SOURCE: Odometer quit working

Suggest you visit this website... http://www.hyperocity.com/volvo240/volvoodometer.htm
Odometer is turned by a mechanical gear wheel, which is the likely culprit.

SOURCE: CAR HAS NO AC AND WILL OVERHEAT

Definitely get the fan problem fixed. I had an older Saturn, and it would do that periodically. It turned out I had a bad battery terminal, it would short out from time to time, and if it did so while I was driving, the fan would cut out and therefore not cool the engine. While I was driving it was usually ok, because air could flow, but in traffic, or stopped, it would get pretty hot. I found that turning the heat on and letting it blow full blast would help it stay a little cooler, it'll just cook you inside the car.

SOURCE: Front AC Blower quit working. Rear AC blower

The first thing I would do is check to see if a fuse is blown or bad relay. Then I would unplug the blower motor with a test light make sure you are getting power to the blower located on the far passenger side of the vehicle under the dash if it has power and good ground then suspect vaulty motor. If you are not getting power at the plug then you might have a bad switch or resister. If it does have a blown fuse remember they usually blow for a reason like faulty wiring or even a in the motor itself. I would also recommend that you change the ac cabin filters behind the glove box if they have not been changed most people neglect them on that vehicle because they are a little more difficult to change, after removing the glove box there is a metal bracket in the way of opening the cabin filter compartment. They wont cause a blower motor to not work, however they do restrict airflow to the evaporator and they protect you from pollen, dust, and even exhaust gases. Hope this helps.

To check for leak in evaporator,charge the system fully,with green neon dye,and use the glasses made for that.Let the ac run a good bit ,and condensation is leaking from the evaporator case,and look for the dye in the condensation.

98 eclipse 2.0 idles high at 2500 rpms an I just replaced the throttle positioning sensor


sounds like you may have a vacuum leak. any air entering engine not passing through the throttle body will cause engine to race. a whistling sound is sometimes a sign of vacuum leak but not always audible. propane is the recommended method finding leak but I find this unreliable. spraying carb cleaner around suspect areas and listening for a rpm change is more successful. just remember carb cleaner is extremely flammable and caution must be used.

Ac system does not retain freon, cannot find leak when using dye.


Most probably the leak in in the evaporator side of your AC system. Look under the car near the passenger side of the rear engine compartment for the condensate drain and see if you find the UV dye there. If so then that is where the loss is happening. If you don't see it there be sure that the condensate hose is not clogged. You will have to get the car on a mechanic's rack to find and clear that problem. You will have that problem if you ever found water in the passenger floorboard after a sharp left turn. Use a long #2 phillips screw driver to clear.

Compressor and fans do not turn on until rev engine


I passed this question the first time I read it, so I will take a stab at it now.
The fans don't come on until the compressor has pumped the freon pressure up to say 150 or 200 psi. And the compressor clutch has to have voltage to engage the clutch.
I wonder if the clutch is going and needs 14 volts instead of 12 to engage ? Or the relay that powers the clutch ?
Speeding up the engine would increase voltage from the alternator.
This is assuming the serpentine belt is tight and everything else is working correctly.
I think I would swap the relay with another and put a meter on that circuit to the ac clutch to see what it takes to engage it.

I've got a 2002 Montana in the shop and the A/C has got a leak. The condensor was replaced 2 months ago and system pressure tested ok. Has dye in it and there is absolutely no trace anywhere. The...


The AC may stop working due to a refrigerant leak from the condenser - this is not uncommon in Montanas built between 2001 and 2003. GM has developed and updated condenser and mounting bracket to help prevent the replacement condenser from failing in the same manner.

I'm not sure why the dye isn't showing.

Usual cost of the fix is around $550.

2004 Dodge Durango. when started it idles high to 2000 RPMS then when on the road it stays at an rpm, you dont have to push the pedal it just goes by itself.


It sounds like the Idle Air Control Valve is stuck. This will give you a fixed idle it can stick at high idle or low or anywhere in between. If you take off the air cleaner you see where the air is getting sucked into a small slot or hole. spray some carb and choke cleaner in there let it sit for about 5 minutes then start the engine. spray a little at a time with the engine running till the idle comes down by itself. This should take about 2-3 minutes. If it wont come back on its own take the 2 torx screws out and remove it clean with carb and choke cleaner and replace. If it still fails it will need to be replaced. MOST of the time cleaning it will work

I have a 98 ford expedition that is leaking the freon out when put in, the air compressor is working, how do i get this fixed


You'll have to locate the leak then repair it. To locate a leak in the A/C system you can add dye to it. When the dye leaks out it will show up under a black light. There are also electronic leak detectors but they can be quite pricey.
