Everything ponts to a bad fan motor/wire connection

Are you sure that the fan you used for test is good .. this is very important cuz if you are not positve about that, it throws off the diagnosis..
I would separate the fan and try each alone .. If you have an amp meter , I would also get some draw readings
Lastly, you could also have a high draw caused by bad wire connections .. the most suspect on these will be at the fuse terminals, at the base of the relays [ there are two, located in slots B and C behind fuse box], at the dropping resistor. and the ground side of the fans..

Checked my fans last night. They draw about 18.5 amps at startup and 11.4 when running on low from the A/C pressure switch. I would go with 25 amp fuses at least.
Unplug one motor at a time and check the draw for each.

Well it turns out that the fan that I used to diagnose the problem isn't so new and isn't so good. What I did was I tested each of the two fans separately. The right one (driver's) is good and spins freely and very fast, no blown fuse. The left one spins very slow and although the fuse didn't blow right away, it did get pretty hot as well as the wiring so I simply aborted the test and called it a day. Also, when spinning by hand, the left one seems to have a lot of resistance but the right one spins effortlessly.I guess I will be in the hunt for a fan. I disconnected the bad one and left the good one plugged. I'm not running the A/C at the moment as I need a recharge so I'll be using the good fan when the engine gets hot. By the way, which fan is the low speed and which one is the high speed (harness).
Again, thanks to all that responded and gave very good advice, especially Arthur who has stayed with me all the way. I only hope that I can provide some assistance to someone else as I gain knowledge and experience with our cars. Thanks everyone!!!

Booo... Hissss..

I knew you threw me a curve ball with that other fan..

..anyway, the fans are wired in parallel, so it will run with just one .
as far as speed , there is no high fan and low fan motor, The speed is determined with which circuit is being used
The low speed is the a/c circuit , using the dropping resistor to get low fans .. and the high speed is the engine coolant temp sensor hitting 105 C and sending power to the fans without the dropping resistor , resulting in full power/high fan..two different circuits sharing common fan motors only..
but with a bad motor , you will blow fuses, no matter which speed/system you are using..
