Narrative:

I received an ACARS message from a company B757-200 on a flight stating the windshield lower power feed plastic cap looks burnt and is hot to the touch. Seems ok but definitely hotter than the others [caps]. I then received a second ACARS stating I mention this since this aircraft diverted yesterday.
