code 7 had a 0 0 reading and code 8 was an 84

does this mean there's no freon left

id like to put some in just to make sure it is even working correctly before i spend money on leak diagnostic. can someone point me in the direction of the fill connection?

literally just got the car running after someone had it sitting a year. have no money for a shop to do anything unfortunately. so i guess i need to reset the code to be able to even install the 134?

here's apic of codes before i cleared them. i then put the can of 134 on and it registered zero on the gauge. i put the 134 in until it was up near the red line. then went back and read the codes

code 7 has a reading of 6 where it was zero before

then i read the other eb codes. only one left is 419 after we drove it around a bit

also i cannot hear any cycling on and off of the compressor. in other cars with bad ac i believe it just cycled on and off

thanks for the info , that is beyond my capability to do

can you look into your magic 8 ball and tell me if the compressor is otherwise ok? or no way to tell from my info

my mechanic told me even if there is simple repair. sometimes replacing one part messes something else up. unsure how that would apply here though. we are still unsure to keep or sell this but were hoping to get the AC working to sell without spending much money
