Help me identify these wires in the engine bay!

[synergy141]

I'm trying to get my A/C working again and there are 3 sets of wires not hooked up to anything on the front passenger side in the engine bay. I attached pics....

Wire 1: There are 3 together. Black with brown stripe, another with Black with green stripe and a solid black wire

Wire 2: Blue with pink stripe, and a solid brown wire

Wires 3: Light Blue and a black wire with white stripe

If I get out to the garage today I will check to see what I can find out.

Have you looked at the ETM for your car?

If not, download it and spend some time.

I think the 3 on the radiator hose (silicone? nice!) are for your AUX cooling fan switch...maybe.

Do you have the switches installed in the tstat housing G?

The three wires are for the dual temp switch I think.
