Pontiac Grand Prix: I need to somehow manually engage my A/C

This answer was rated:

I need to somehow manually engage my A/C compressor

Hello I'm Paul and I will help you with an Answer to your Question

you can pull the relay and then put a jumper wire between the switch pins of the relay

G8 and E7 in the diagram I am attaching

the relay itself should show a schematic on it also

What could I use for a jump wire?

you need a peace of wire and strip both ends so you can insert into the pins under the relay

A paper clip can work but I would be careful if you go that route because it can get hot and burn your fingers.

Normally I find an old peace of electrical wire and cut a short peace and stripe both ends

I'm trying with a household 110 whit wire I think it's goin in but nothing happens .. If I am reading the diagram right is the two pins on the right need to be relayedI think

the relay itself should have a diagram also

 

and the bottom usually has the PIN numbers

 

a house wire would work... do you have a test light?

if you you can take a picture of the Relay ... the relay diagram and the pins under the relay you can upload them using the paper clip above the text box

and I can verify you are jumping the right ones

I tried all possible connections but nothing happened.. Is my compressor bad?

you need a test light to see if your getting power to the relay pins.

a volt meter or test light for testing.

and I can tell you what to check

 

if there is no power getting to the relay jumping it will do nothing also if you have a bad ground somewhere could do the same.

Have you checked the AC clutch fuse 30 (10 amp)?

to help you further I need you to have a test light or meter and I can direct you on what to check

So I definitely figured something out I switched out that relay with my highbeam relay but I was wiggling at around the same time they're the same kind of relay and my compressor engaged only when I pushed in the relay very hard.. And it seems real sensitive to touch you can hear a little snapping in there does that mean that I have a bad fuse board?

you could have a bad connection there or a loose wire under the pins.

do you see any corotion?

if you move it around and tap on it does it stay running?

No corrosion .. But it. Does turn on and off if I wiggle it..

you may need to open the fuse box and look for a bad wire or loose wire.

you may need to replace it but you might want to see if it can be repaired

How hard is it to open up the fuse box so I can look at the wires I hate wires by the way lol... Everything else on my car I can fix no problem but wires really intimidate me

different boxes are different

 

usually there are a couple of 10mm bolts that hold it down and often there are many clips that you need to pry open with a flat head while trying to pull it apart.

there is no detailed information in my databases for going inside the panel but you pretty much need to look at it for bolts and clips

you may also want to disconnect the battery first so you don't have any issues

I would think a shop would charge you around $100 to go in and look for the problem

Do I have to take all the fuses and relays out to take the face off to look at the wires?

normally it will come apart with the fuses still installed

it usually splits in two

so it looks like it finally died :(..I opened everything up and you cant see wires back there because the box is separated into blocks inside the fuse box that just have the wiring harness wired right in. My question is how hard would it be to install a new box with wiring and everything ? Seems like it is a last resort but the A/C relay is completely not making the connection anymore..it pops a little but doesn't work at all anymore.


thanks
