202 aux fans not working

[freespool]

have 96 C220 202 chassis. just put new compressor/clutch cause clutch wasnt engaging. also drier. compressor comes on now and cools but pressures start to go out of sight. one fan came on briefly. tested and found other to be bad. replaced both with a new pulse module. neither fan comes on at all with all the new parts. when i disconnect the pressure switch the compressor shuts off. when i disconnect the temp switch it stays running. once in a while the fans will try to run on low stage for few secs then shut off. has me stumped. any ideas?? i get a voltage signal at both the pressure and temp connectors. i get resistance reading on temp switch. cant reach pressure switch to read w/o removing from drier. any ideas??
