Ok, I see what you mean.
Yes I have 1 single serpentine belt.

So, the situation remains. You need a relay to eliminate the Klima, or, you need to do further testing to see if the Klima's signals are correct. Or both. |

I would love to do further testing
I'm going down to the store right now to get couple of relays 1 alarm system 2 auto antena 3 cruise control. I will be back in half and hour and check this Thanks man

ok back from the store,no relays
cruise control still not working, changed all the vacuum hoses almost that I can see, it worked for about 10 minutes, 3 days ago then I switched it off comming off the freeway and never came back on, there is also a vaccuum hose connector that comes right out of the injection pump that broke, I got some regular vacuum line in it but I'm going to replace it with the right part tomorrow from the dealer. Cruise control fuse is fine, maybe still a vacuum problem

Start the engine. Jump sockets 5 and 7. The compressor will start. Measure ac voltage across sockets 9 and 11. You need a sensitive meter for this. The nominal value is .3V If you don't get close to this value. shut the engine off and measure the resistance across these same sockets. The proper value is 530 to 650 ohms. My data comes from the W126. However, I'd bet the W124 is the same. |

Now do the same check on sockets #1 and #2 with the engine running. This tests the engine RPM signal from the EDS. Nominal value is 2.8V AC voltage, at idle. |

So, both speed sensors, check out. There is only one other possibility, other then the Klima, itself. Put the Klima back in place. Find the low pressure switch on the dryer. There are two switches on the dryer. The upper switch, in the center of the dryer will typically control the aux fan (on the W126). The lower switch should be the low pressure switch. Jump this switch and see if the compressor will start with the Klima in place, the engine running, and the middle button pressed on the PBU. If the compressor still won't engage, then I'm fairly convinced that the Klima is NG. Like I said previously, if you get a relay, we can bypass it. |

Ok
I will get a relay but let me know exactly what kinf of relay from Auto Zone or Kragen. like what numbers on it etc ICE CUBE relay right? on the second part I have no idea where or what the dryer is. where is it located? how does it look like? thanks man
