AC stops cooling

AC stops cooling after some time Dodge Neon

If you have a problem where the AC stops cooling after some time Dodge Neon, read this post. The low pressure switch controls whether the A/C clutch engages or not and it should be a simple yes/no situation. If your A/C cuts in and out, or A/C shuts off, either the pressure in the system is correct or it isn’t. But in some cases, an internal fault with the switch itself may turn a simple problem into one that drives you crazy. Some shops are finding that the mechanical switching components inside the low pressure switch behave erratically, preventing power from reaching the clutch at times, and at other times allowing power—despite the fact that there’s a full charge in the system. If you get weird A/C operation, try changing out the low pressure switch. Since the operation is erratic, testing it isn’t much help. It’s a fairly inexpensive part, so changing it may be your best option.
