do u have the compressor working yet?

The fault codes will make the ECC PREVENT the compressor from working until the faults are cleared.

48 should clear, but 66 may not. You sound like you need a recharge, but try to clear the codes anyway, and see if the system starts working again.

it didnt start working yet is there a way i can get 66 to clear do i need to recharge it?

Did you actually use the procedure in Techinfo to clear the codes, and the 66 didn't clear, but the 48 did?

If that'* the case, you either have a leak, or a pressure sensor is bad. Have the system checked, repaired, then recharged with freon.

wha would YOU check for will

That'* what I'd do. If you have a leak, you need to find it before you recharge.

wha about a sealant to seal the leak?

The gunk you just put in the system? No. It'* a joke. Get it fixed right.

ok
