A/C is not working

[thekidwithquestions]

Yes, is there a like relay you can substitute short term.

idk lemme search around...

Please post a picture of what you are referring to, but generally black ends on terminals mean that it over heating due to resistance and/or too much amp draw...

See if it does anything if you push in on the speed control switch.

Jump out the power to blower positions on the relay base.

Alright it wasn't the relay, I swapped in the starter one and it still didn't work so I put the blower one in the starter and it started fine

You need to really look close at the dash switch again -

Good post- my 06 was doing that- a new switch and it all works good now.

This, at that point I'd suspect the connectors have been damaged as well.

I tried thing one and got nothing.

You can jumper out the fan speed selector harness terminals between the power in and the different speeds.
IF all the fan speeds work; then the problem is certainly the fan speed selector switch.

I check the switch and it looks fine, no melting or anything.

Dont go by looks- it can be shot inside- also look over at the zone selector , it has switches that tell the A/C when to kick on as well.

how do I check if it working then? Also what's a zone selector?

The zone selector is the right switch that has the colored vacuum lines- it does foot, defrost, a/c - it is all part of the control module- I replaced mine for 150.00 bucks at a parts store- the whole deal- worked out nice- but if yours is a late model save your vacuum selector off the old one/ their are some diameter changes in later years.

That will be it- heat gets them- they sell various parts but the whole unit would be a good investment- good job on being persistent.

What year is that buddy? I see.

My son does what you do. Learn that trade. No such thing as a poor electrician in our area.

I don't know the availability of your year parts, but I bought a used control panel from ebay pretty cheap that matched up with my '06. It wasn't an A/C version, but I only needed the fan speed part. I removed what I needed and put onto my control panel.
