If that is not the case, and the low beams never come on regardless of switch position/condition, then you would be correct. It would be far easier and quicker to swap relays though... if the problem reverses then it is a bad relay, if not then check for main power at relay (30), switch power (85) then if those check out, make sure you have continuity from output (87) to the light sockets. Finally, don't forget the relay and bulbs also need a good ground, so check (86) and the bulb sockets are grounded.
The OP needs to clarify what exactly he means by "which in turn means all 4 of my lights are on" Does that mean all 4 light truly do come on, or merely should come on?

Here are some visual representations to help in understanding whats going on. I didn't make one showing power not getting to the low beam relay at terminal 85, I would start looking for voltage there.
High Beam, four lights on:
Low Beam, Good Dimmer, Bad Relay:
Low Beam, Good Dimmer, Good Relay, Bad Connection: (the bad connection could be anywhere between the relay and the lamps.)
Low Beam, All Good: (this is what we want!)
