The coolant in the reservoir of my 2005 Lexus rx330 is completely solid.

What is your question?

Check engine and vsc light on. Ac stopped working. Dont hear ac cycling on/off. Temperature gauge doesn't show overheating. Coolant isn't brown. Its warm summer temperatures right now.

What makes this problem better or worse?

Ac was working until I disconnected battery terminals and reattached.

How long has your 2005 Lexus RX330 had this problem?

Just noticed solid coolant tonight.
