This has been discussed many times here before, and I thought I would bring all of the information together in a "how-to." I am going to attempt the semi-permanent cleaning repair this weekend. I will let you all know how it works.
Problem: A/C and Recirculation lights flash on and off intermittently.
Reason: HVAC Control head unit is worn.
Affected Model Years: 1997, 1998, 1999, 2000, 2001, 2002, 2003
Semi-Permanent Fix:
1. Replace unit at a cost of $100 - $150.
Will return in 2-3 years depending on use.
2. Clean existing unit with directions provided here, at no cost.
Will return in 2-3 years (estimated) depending on use.
