1993 300e 2.8 For several years I've dumped a few cans of 134 in the system and it lasted a month or so. Only did this during the hot months. This year I did the usual 3 can dump and it lasted a month so I thought I'd try some of that AC sealer stuff. Installed one 8oz can of AC sealer and immediately 2 cans of 134. It lasted a month. Today I dumped in 3 cans of 134 and it won't cool or kick on the compressor.

Where do I start? I'm assuming the seal on the compressor is bad but not sure.

Any comments or advice would be appreciated.

More likely its the evaporator. You're toast (in more ways than one).
