So in the process of converting from R12 to R134A, I noticed the passenger fan behind the radiator does not engage. The driver's side fan is on when the A/C is on. I've replaced the fan from the pickNpull and it still doesn't work.
I've read some confusing content that only one fan comes on and it's if the car is overheating.
Can someone clarify? Should I be worried about the other fan?
It's worth mentioning the car does not overheat. Ever.
