Attention 1991 Previa Owners

I just bought another 1991 Previa last week. This is the second '91 in my "collection" and I was told by Toyota that was never taken in for the service campaigns. There are two on this model year- the expansion valve and the right windshield wiper arm. There were four others that I had looked at purchasing and three of them had already had the expansion valve taken care of but none had the wiper arm replaced. This makes me believe that most Previa owners are unaware that these campaigns even exist.

If I recall, haha, there was also a radio-catching-fire recall.
When I had my wipers done, the dum fu.. didn't put the arm back on correctly and shortly afterwards the splines stripped. Unless you know the mechanic, get work done at your peril.

Edit. Toyota has a recalls page where you can enter your VIN and find the recalls for any model. https://www.toyota.com/recall
I haven't checked to see if it is useful.
Some info here too, which seems right for my '91. Scroll down and look on the right side of the page for your year. https://repairpal.com/toyota/previa/recalls
