Hey what's up i recently bought me a Monte Carlo with switches, and the rear won't raise. It will raise for a second but will not hold the pressure it needs to hold it up. I checked the hose and it is fine, so what else could be making it do this. The front works fine it is the rear that will not stay up. it's a 2 pump set up, 10 switches, and i'm really tryin to learn the technical side of hydraulics. The nearest lowrider shop is a couple hours away so i really need some advice on what MIGHT be the problem so i can break it down a bit. Thanks in advance to anyone who can help...
