Dash air leak

Have a 03 American Tradition, will not hold freon, leak appears to be in hoses from compressor to coil.
Unable to trace due to belly pans, suggested running new duct on bottom of motor home for hoses rather than removing pans and tanks
Anyone have a comment?

Has anyone added dye to the system and then traced down where the leak is located exactly? If not, then you need to find someone who knows how to work on automotive type air conditioning systems.

Since it is blowing out tge gas then locate some adaptors or old charge hoses and connect an air compressor to the system and charge with air.

Get soapy water and spray things down and also listen.

Compressor shaft seal and every hose end connectors are first suspect.

Second would be where anything rubs.

Charge manifolds are cheap depening on gas type.

You can use gages in manifold with conttol valves to control the air connection then monitor the air pressure for leaks after repairs.

This will require full vacuum of system after repairs for proper recharge.

Do not recharge until you can get it to hold an air charge for a week or do.

Also check pressure BEFORE doing anything.

Get a manifold so you can see where you are at.

I would suggest using nitrogen to pressurize the system in lieu of air. This will reduce the amount of moisture you get in the system.
