How do I check Blower Motor circuit on 98 Dodge Dakota?

I have the Haynes repair manual and it says to bend back some screws to release a wiring harness... I could not find any harnesses like the one described in the manual...



Can someone point me to a step-by-step guide with pictures? Or maybe offer advice to what other reasons would cause my AC to not work anymore?



Here is the summary of what happend(keep in mind i used A/C as well as the "outside air" setting):



First, it worked fine for a LONG time (over a year).

Then, it started going in and out; sometimes working, sometimes not.

(also, once it came one, it stayed on until I turned the vehicle off)

Then, it started getting harder and harder to get the air to come on.

(and once it came on, you could barely notice it with your hand right against the vent)



Now, no matter what strength (high, low, med) or setting (A/C, vent, defroster) sometimes you can feel a hint of wind coming from the vent.How do I check Blower Motor circuit on 98 Dodge Dakota?
Take a pair of jumpers wires "alligator clips / wire" and bypass the circuit relay. By doing so the fan should turn on full power, if not it's the circuit. Also check your ground wires. It might also be your compressor motor going out. As they get older some compressors get harder to cycle over.
