Trying to diag a cooling fan or A/C issue and looking for y'all help.

While driving A/C performance is ok but not great. One issue I just recently discovered is my boss has the same truck but his fan go into Hi mode while mine never do. I pulled relay and jumped the Hi mode and it began to work. Thinking maybe the relay was bad I replaced it but didn't resolve the issue and looking for y'all input where else I need to check.
