04 Astro Van door locks not functioning properly with evo all and compustar

Question

I have a customer with a 2004 Chev Astro van that I had installed a Compustar CM800s and Evo-All in and the keyless when used with the compustar remotes do not operate correctly. The unit will not unlock the passengers door completly,( unlocks half way or acts like it is stuck  ) but operates normally with factory remotes and with relays installed. Everything else operates as it should.Firmware version on evo all is 4.06 and have tried various evo-all units.Units were flashed with both hardware versions of flashlink updaters. Compustar is also flashed to current revision.Evo- all was set in fortin and ads bypass mode in options menu. The only method I did not try is hard wire method.I also regrounded the unit twice to eliminate possible ground issues. Any ideas on a possible solution to this?

Thanks

I have since hardwired the keyless with relays and the problem is resolved.
