Narrative:

Location: mateo VOR 160 degree radial. First officer was flying the mateo six arrival to mex. I had the 248 degree radial of mex VOR for the lead in set. At 7 DME of mateo VOR, the first officer switched to the ILS to runway 5R. As I was identing CDI was off the wall, so the first officer started the left turn to intercept. I also changed to ILS frequency and both CDI needles showed we needed to go left, but the tower came on and told us to go right to intercept final approach course. We looked ahead and to the right, saw the runway, and made a normal landing visually.
