Sounds like you don’t know what your doing. Before you spend anymore money on parts I suggest you take to an AC shop and have it serviced. A lot of shops are running AC specials.
for full a/c service, one must evacuate the system, and provide a brand-new fresh filter/dryer~ should be a "site-glass" where you can see the degradation of the desiccant canister, pressurize gradually to the required spec, say 28 psi with R-134
