SOURCE: No volume control with 2 faders on Mackie CR1604 mixer
If all other functions work for those channels, the most likely problem is the fader itself. These can fail and operate more like switches rather than faders. Without witnessing the behavior, I can not state that for sure. While these mixers are not the hardest to work on, they are time consuming. The faders can be purchased from Mackie directly. If you need to have this repaired, any shop that repairs audio gear should be able to erpair this for you. Where are you located?

You can purchase the channel faders directly from Mackie Service Dept., you can replace them yourself if you're good at soldering - HOWEVER, be advised that disassembling the unit to get at the faders to replace them will require a lot of time and patience if you've never done it before. If the faders are not moving smoothly, it's possible that the wrong type of cleaning spray was used on them and there's a possibility that they could stop moving and controlling sound.

Unless you are in super humid environment, this is more likely a crack in the circuit board OR a bad connector on a ribbon cable. Also BROKEN or cold solder joint for a connector pin through the circuit board.
Good way to cause this with ribbon cables is to NOT distribute the load when pulling them off. Often the wires near the edge are stretched and make poor contact with the little forks that pierce the insulation.
CRC226 is a good product to use for contacts. Available at Home Depot in the electrical department. Blue spray can. Use sparingly.
SOURCE: Hi, Model: Mackie 1604 VLZ PRO
You may be getting a small amount of cross-talk. How high are the gain settings and sliders when this occurs? Also, can you describe the overall setup that you are using? I'll check the prints, but you should not be getting any volume unless the gains are maxed.
