Yep, Both lights should go on and off together.
and Ill give that a shot Billy Bob. another problem is that I cant change the wiring to Light #1 as the wall was completely finished by the previous owner, will this make a difference?
Do you then say you have 3 travelers instead of 2?Yes, that's called a California or coast 3 way...
This assumes two travelers between the switches.
Assign each switch a number.
With switch #1 & switch #2 down, light is on or off?
With #1 up & #2 down, light is on or off?
With #1 down and #2 up, light is on or off?
With #1 & #2 up, light is on or off?
In principle, with the answers filled in, the problem(s) can be pinpointed.
Test cases welcome. . .
Taking only the case shown above, if you step through on a piece of paper all 3 ways of hooking up the 3 terminals of a working #1 switch to 3 wires and with switch #1 in both positions [6 diagrams in all] I don't see how this outcome is possible unless you have #22 wiring with 3 travelers.#1 down, #2 down - lights are on
#1 up, #2 down - lights are on
This assumes two travelers between the switches.
Assign each switch a number.
With switch #1 & switch #2 down, light is on or off?
With #1 up & #2 down, light is on or off?
With #1 down and #2 up, light is on or off?
With #1 & #2 up, light is on or off?
In principle, with the answers filled in, the problem(s) can be pinpointed.

It would be my bet that the upstairs switch is not functional due to miswiring, bad switch or it just plain never worked.
This is awkward, but...
