Just got my car last week and of course its been raining all weekend, anyhow I used the windshield wipers and noticed that it was either all or nothing, the intermittent speeds didn't work at all,had to be either on or off. Is this a common problem? Can I fix the existing system or do I need to replace the motor or turn signal switch?

Most likely a delay module.

I haven't got my FSM yet, can you provide some more details? Thanks.

I believe that it is inside the wiper motor. They used to have them at auto zone

Hooked on Vettes

Bolted to the front of the wiper motor assembly is a black plastic cover. I believe it's held on by 3 or 4 torx screws. The cover contains the delay circuitry.

You can buy the cover by itself but it's probably cheaper to buy the complete wiper motor assembly and just replace the cover.

Photo 1 shows the two connector plugs on the cover. Each have 3 wires.
Photo 2 shows the circuitry in the cover.

One plug has
Pin A Brown wire
Pin B Black wire
Pin C Pink wire

2nd plug has
Pin A Gray/White
Pin B Light Blue
Pin C Gray

With the wiper switch in LO
Unplug the two plugs at the wiper cover.
With an ohm meter measure the resistance from Pin A Brown wire on one of the plugs to Pin B the Light Blue wire of the other plug.
Should be 24K ohms.
As you rotate the delay band you should measure up to 1.2 Meg ohms.

If that's correct the problem is in the wiper motor cover.
If the results are not correct the problem is in the wiper stalk
