My car's air condition has stopped from working. Well, what it does is that when ever i step on the gas it blows out hot air and when i brake, it blows out cold air, what can it be wrong? why is it doing this?

More than likely the A/C is weak or has moisture in the system.

Here are a number of guides that will help with what we need to do to start.

First we need to check the pressures using a gauge set.

Once we know what the pressure is on the high and low side with the A/C on and off, then we will have a better idea what to do next.

Below is a chart that you will need to figure out the possible issue. This shows the correct pressures based on ambient temperture. let us know what you find with this and we can go from there.

Thanks
