I've seen mention of a TSB concerning the replacement of relay 90987-02022 with relay 90987-02028, but what about relay 90987-02020? We have an '03 Highlander and this past October I learned from my wife that the light had previously been blinking, but she would turn the A/C switch on and off until the light stopped blinking. Unfortunately, I was heading to my sister-in-law's funeral in Louisiana with our 3 and 5 year olds (hence the need for A/C) and ultimately after many hours in a dealership and many dollars spent on a new control unit (55904-48210), finally was back on my merry way with working A/C. Fast forward to today and the wife tells me the A/C isn't working and the light is blinking again . . .

Is the 90987-02020 relay a known problem or is there something else I need to look for (we are wayyyyyyyyyy out of warranty?
