Check your relays. Also, your fan switch may be seeing its final day. If you have to change the fan switch, swap it with a aftermarket one. They can turn on the fan as low as 180 instead of 220(stock)

Re: Fan Problem... To Hot...
I run the fan switch that's on at 200° and off at 185°. Works great for summer and winter. Keeps the car cool but doesn't run all the time.
Are you still on the original R12 A/C? You might be a bit low on R12. If that's the case, your passenger fan probably isn't kicking on because it's not getting high enough pressure when the A/C is running.
