dahozzman Posted July 1, 2003 Share Posted July 1, 2003 There is a lengthy thread on this subject with error codes and all sorts of great technical information. But, I was lucky with a back to basics approach. The HCV is easy to access being near adjacent to the fire wall on the passenger side. It is held in place by a single 7mm nut that you access from the bottom. Remove the nut, two vacum hoses, and unhooked the two wire electrical connector. Now, logically, what we have is a magnetic valve. When the heater is turned on, electricity runs to the HCV moving the valve much like a relay. Further logical thinking, I'm in So Calif, so how often is the heater used? Conclusion, the valve simply got stuck from lack of use. Repair, a couple firm (not HARD) wacks against my work bench. Cleaned the electrical connector spades for good measure. Reinstalled. Everything works fine now. :) Lucky... probably. but certainly worth a try before replacing with the expensive Lexus replacement HCV. Hoping you have the same luck as I did. Drive well.
