Thank you for using Just Answer for your needs. If the a/c does not work then there will be no water draining from the evaporator drain tube.

After you clean the water up from the back, when does the water come back? Only after it rains or going through a car wash?

The a/c compressor (cooling unit ) stopped working a long time ago however I still used the fan which stopped working just over a week ago . Could this be related ?? I just stepped outside the car and saw water coming down from around the back of the car area (around the back tires area . I haven't washed the car and although it's been raining a little I had the windows wide shut ... Please e-mail me XXXXX@XXXXXX.XXX. Thanks

Also after I dry the carpets with a towel the water comes back within 2-3 hours .Not a huge amount but enough to be constantly drying . Also i noticed there's water in the front seat carpets also but much less than in the back ...

I take it that there isn't a sun roof on this 1988 model year Corolla is there?

I just want to be sure.

No - it's a regular roof

Thanks. The body itself has a leak then. Is this something that you will want to pull out the interior trim on and try to look for the area of leakage?

Or would you prefer to have a shop do this?

But where is the water coming from ?? from outside the car or a/c or other part inside the car . I have no alternative but take it to a shop. Do you think the repair will be expensive ??

The water will not be coming from the a/c as it does not work. It will be from the body somewhere in the back.

What will need to be done is the water cleaned up and area dried. Then they will remove all the seats, carpeting and interior trim around the area in question.

They will then have someone inside with a flashlight and someone else on the outside with a water hose soaking down the car. Starting at the lowest point and working slowly up. The tech inside will watch and yell when he/she see's water coming in. At that point the person outside will stop and that will let them know where the water is coming in from. This method has to be done in order find the exact location. Otherwise it would just be a guess.

The cost should start at about $65-80 for the 1 hour diagnostic time.
