What have you done to your MSP today?

My key fob stopped working. I press the lock button and the lights indicate locking and un locking but, the locks dont move. No clicking noise that indicate attempting to lock either. Any thoughts?
 
not sure, have nothing to check it.
You're probably wasting your time checking all the other components. I'll give you a way to narrow it down.

-Start up the vehicle and locate the A/C pressure switch under the hood on the driver's side and unplug the switch and ground the Green/Black wire and see if the A/C compressor operates.
-If the A/C operates, then plug in the pressure switch and backprobe the Gray/Red wire and ground it and the A/C compressor should run, if it does not then either the pressure switch is faulty or there is low pressure in the system.
 
So my car won't stop squweeping so loud no matter what I do, I changed the belts still squweeling .. I Tryed this belt conditioner spray, nope... It's getting wors every day, is use to stop after the car warmed up now does it all the time, when I'm turning, when I stop and go.... Any suggestion.....?

what belts did you use? i used gates once and had that problem, switched on mazda oem ones and didn't have the problem anymore. Also try to tighten them, they could be a little loose still

how does one recharge an AC system if thats the case?
The correct way? Or the do-it-yourself, not-the-best way just to get some quality of A/C performance? Best way is to evacuate the system. Two reasons why. The first is that (if it's a new machine and not just a vacuum machine) it will tell you the refrigerant, if any at all, that it took out of the system. That way you can see that you only removed .8lb and it's a 1.3lb. system. That tells you that you were .5lb low. Second, you can do a leak test by seeing if it will hold vacuum.

Now, if you determine that the refrigerant level is low, you can go to a parts store and purchase a can of R134A that has a gauge and hose attached and add refrigerant that way. The problem is, you don't know how much is in the system or how much you're adding which can create a whole new set of problems.
 
Okay, ill give those a try, and if that doesn't work... Cuz this noise is so annoying lol
When it comes to belts you have to get good quality products otherwise they will squeal and wear out faster. There's another brand that people on the forum like but, I can't recall what it is. GL
 
Is it normal fo rthe refrigerant pressure to get low? Or is there a leak? I checked quickly at all the piping and I didnt see anything that could be an issue.

So you're saying I should have a pro do it then?

Yeah, but this is coming from someone that manages a shop, and I don't have to pay to use the shop/equipment. Most places are going to charge, at the very least, an hours worth of labor. $100 is worth the hassle to me and could quickly get you an answer to your problems. Now if they do an evac/recharge and refrigerant levels are okay, they probably won't charge you to spend more time diagnosing the problem. They may come to the conclusion that it's a failed part that you could replace yourself. Perform the test procedure I gave you first though. I'll try to help as much as I can without being there. LOL
 
lol ok, i appreciate it.

Real quick tho, would the low pressure also cause the fan to not come on, or just the compressor? Because either come on for me.
