7 Series :: Low Speed Aux - No Fan Operation With Compressor On
Oct 15, 2010
88 735il
No fan operation at what point on the gauge does the hi speed fan cut on? No fan operation with compressor on.
I have checked the fan works bypassed: Replaced the fan sensor and temp-2 sensor, coolant sensor works.
I have checked both relays hi and low both have voltage and fuses are good. It seems like the resistor maybe the issue I will check that today.
I never let the car heat up over 1/2 way which maybe why the hi speed fan does not come on unless bypassed. What value resistor is?

Lexus LS460 2008. My AC compressor cuts off at low speed if i accelerate or turn it off and then on it comes back. It never happens at highway speed only in town could it be relay problem? where is the AC compressor relay located?

When I am at idle, the compressor keeps turning on and off every few seconds. It seems to work fine while driving. What do I need to do to fix this?

My compressor on my 92 Ranger did not have any clutches on it. Where they went. I got a compressor off of a 94 at the pick and pull. It was charged and the compressor turned fine. Brought it home and tried to install it. My hoses in the back of mine(92) are different than the 94. I went back and got the hoses, condenser and evaporator off of the 94. Put it all together. The high pressure hose on the 94 has some sort of switch on the high pressure side. What is this switch for and how can I wire it in to the electrical system on the 92? I assume it is some sort of pressure switch that allows the system to flow. I'm getting 30 pounds on the low side and 150-200 ponds on the high side. Also, when I increase the RPM's, the compressor kicks on and off. It's not like it would or should normally but fast.

I have a 2001 ranger 4x4 4.0 L with what appears to be a unique a/c problem. Over the last week the compressor will not kick on immediately and seems to randomly decide when it is going to function. Once it starts, it runs properly and cools well, until I turn the engine off and it is back to square one. We have checked the coolant level and it is full. the problem seems to be getting progressively worse....At first it took about 15 minutes for it to decide to trip, then 30 minutes, and yesterday I drove for over an hour and the compressor never kicked on.

I've got a problem with my AC Compressor, with the AC on the compressor engages then disengages about every 5 seconds. Now I looked into it and some people said you can remove a washer to remove a gap. Do you think I should change the whole unit? Looked online and I can get one for $100. If I do work on the AC compressor to try and fix it or remove the whole unit do I need to drain any refrigerant etc etc. I have a hayness repair booklet and they said that to remove the ac compressor you need to get it drained by professionals. Although on the compressor I only see a electrical plug and no hoses.

I have a 2001 Mazda B3000. The a/c compressor is coming on while I'm running my heat. The air coming out while the heat is on stays warm. However, when I was running the A/C during the summer the air would start blowing out warm after it had been on for a while. Several people told me it may have something to do with the blend door or blend door actuator but both appear to be working fine. What it could be?

101,400 miles on car. Started noticing about 2 weeks ago, at idle, and as pickup up speed, a whining noise coming from the engine bay. It has gotten a little worse, so I started trouble shooting.
Basically, at idle, its somewhat annoying, but as you hit 20-30mph it can be more annoying if the radio is off or at low level. If Im sitting there in park, and its whining away, all it takes is me cutting the A/C knob to OFF, and then quiet as a mouse.
So, other than the compressor going bad, I can't see anything else related? I always hate when AC problems show up, they are never cheap....

So I just got done with my first 2 problems of the month with this truck last week. Front end and emissions along with spark plugs. Now, 4 days later this morning, I'm driving the truck trying enjoy the investment, and the AC compressor starts seizing up and burning the clutch. Unrelated but also worth noting, about an hour later the brake pedal gets real soft and the brakes get really sloppy at stopping the truck. The truck also stalled (auto trans) crossing a highway, luckily it was 5am and no traffic was coming.
I'm at $6k invested on a truck with 116,000 miles, and I've only put 6,000 on it. The repairs don't stop, and I've got many more ahead. Like rear suspension, axle, trans, and radiator fluids, and paint, to name a few. Any suggestions on fixing the AC before I drive this truck into a lake?

I am in the process of removing the lower intake on my 99 Ranger 4.0. I was unscrewing the AC Compressor to get it out of the way and also started to unscrew a bolt on the backside of the compressor because it wasn't moving well due to the metal tube on the backside. I think this is the tube to the condenser? Anyways it started spraying air and green fluid everywhere. I got it to stop for now but if I tighten or loosen the bolt it seems to spray. Also it looks like a green o ring or gasket of sort is showing now which I don't remember. What is it and what should I do?

This is a question in general about Fords. My 98 Ranger doesn't do it. He's got a 1987 Ford Mustang 5.0 with original factory a/c. He changed his compressor to a used one and it started running all the time whether the swtich was off or on. He said he switched back to his original compressor and it still does it. I figured it might be something common for Ford a/c systems so I figured I would ask. I'm not sure why it would be unless the mode switch was bad.

When I turn the control to heat the AC compressor kicks in. If turned to vent it does not kick in. Was this just a design flaw.

I have a 2003 ford ranger xlt 4.0L and here recently my ac compressor has been making a loud click noise engaging even though i am not using heat or AC, so when it engages the rpms drop and almost wants to stall and it does this in about 10-15 sec. intervals, but when I am driving it acts fine. What is going on here, I recently had a vacuum leak and i found it and fixed it, and now this issue just started.

I have a 91 735i, 4sp auto, 3.5lt. Usually around constant speed of 40-45 the tranny will downshift then up then downshift an sometimes it will downshift to 2nd which scares me thinking it might downshift to 1st an explode the engine or tranny. If I engage cruise control it does not downshift. This does not happen all the time but when it does it can be very severe with jerking and slamming into an out of gear. The trans has a dipstick and the fluid does not look bad. I replaced head gasket and it was doing great for about a month and then poof the downshifting started.

I have a 1998 F-150 and I have a squeaking noise and I can only hear it when I am in in first gear at low speed and when I'm in reverse backing up and goes away when I press the clutch pedal. I'm thinking its either my U-Joints or Throwout bearing.

My supercab 2WD has about 100,000 miles on it. When I hit the brakes, the ABS kicks in at low speed (less than 10 mph) even though the tires are not slipping.

Not only will it not go into gear, truck will not start unless clutch is to the floor, and in neutral (it's only possible place) if you pick the pedal up 1/4 inch off the floor the odometer starts spinning around 1 mile in 5 seconds.... if you lift it any more it kills the engine like you shut it off with the key.... odometer reads 99,004 miles now (the last 2 are mine) I bought this truck like this ....

The wipers on my '99 SW1 are becoming intermittent in operation. The intermittent speeds change, the set speeds work, but all operations are not stopping when turned off. They do turn off when I turn the ignition off. I think it is the multiswtch on the steering column, but haven't done much troubleshooting yet.

My son just purchased a 1996 Ford Ranger 2.3l 5 speed it is a nice little truck. But I have a question when you press in the clutch it acts like the choke has come on it idles way to high. When you come to a complete stop it is a few minutes before it goes back to its regular idle. Is it suppose to do that?

1999 (built late 1998) Ranger 2.5 stick 2wd single cab. If I get much over 75 MPH the speedometer will reverse direction despite increasing speed. If I then let off the throttle completely, the speedo will jump right back up and indicate the correct speed. Continued operation without letting off the throttle to let the speedo recover will trip the ABS fault light, probably due to the erratic signal.
Disconnecting RABS module has no effect on symptoms. Speed sensor in the rear axle has been replaced already (by me) and the new unit ohm'd out good. Wiring between GEM and sensor checks out as well, good continuity (< 1 ohm) and no shorts to chassis ground. I wish I had an o'scope to take a look at the waveform, but I don't at the moment. It is on my future tool purchase list.

Tried reset by holding while it went back, up, then down, then forward, still one touch operation does not work.
