Ford Excursion :: AC Compressor Comes On For Approximately 1 Second And Goes Off
May 5, 2017
Well I've thrown out the situation of having low freon for discussion earlier and of course consensus is a leak. I added freon by way of one of those guage on the can deals and it seemed to be mostly ok for a while. Today it was around 90 degrees--doggy and I were on a road trip. What started off as a comfortable trip became progressively warmer. I noted the rear air was blowing warm air--not "not as cold air" like what you'd expect from the vents being in the ceiling. Got back home and hooked up my new manifold gauges I had ordered which of course, were in metric.
Long story short, I added some freon but while the low side pressure seems to be in the proper range, the high side pressure is very low, as in not much higher than the low side. The compressor comes on for approximately 1 second and goes off. Both sides have a pressure drop when it comes on-maybe the low side dips a hair below ideal but I am perplexed-or actually lacking knowledge. I know this is going to be a professional's issue for me, but what could be going on. I read a little on the expansion valve but I guess I am wondering if there is anyway to narrow down the problem--guess it comes from always trying to learn stuff.

I got a 04 V10 6.8L excursion with now all of a sudden the clutch won't engage in the compressor. Is there a shut off switch I don't know about or do I have to replace the whole compressor.

Checked fuses, relays, low pressure switch, switch on high side line. Compressor runs and gets cold when voltage is applied to compressor.

So I was doing my coolant flush yesterday and turned on the heat, both front and rear, to move any old coolant out of piping and cores. I notice that the rear was not blowing as "warm" as the front.
I did notice that the compressor was clicking on and off the whole time. A/c pipes coming off of accumulator were freezing up/getting cold/frosty.
Is it normal for the compressor to do this when the heat is on?

I noticed the tube coming of the AC compressor (I think that's what it is called) have no insulation on them and are open in the engine compartment. I can't stand how poor the AC is already, so I'm looking at insulating them. What I could put on them that would be effective yet safe in the high heat of being under the hood?

I think the top AC line that runs from the back of the compressor is leaking on my '01. It looks straightforward to replace, but I don't have any way to evacuate or recover the R134a refrigerant. Is this something that an AC place has to fix, or is there a way to do this on my own?

After driving my Windstar approximately 30 miles or more when I stop and get out I can smell gas. I see no leaks or any gas build up any where. Is there something that maybe is causing too much fuel to be going to the injectors??? which probably would also be tied in with some of the smog equipment.

I have a question about a possible leak. As I never really paid attention to it until of recent days, I noticed that my a/c is switching to defrost while driving for approximately 15-20 seconds then I let off the petal. Would it be time to search for a leak or could it be a solenoid issue. Also why we are on the subject would this have a negative effect on my mpg. I'm usually around 9.5 hwy and 8 around town, 6.5-7 towing 10k trailer. 06 350 cc lb v10 4.10's Factory 275/65/20's 69k miles...

Just joined today, I have a 2003 550 7.3. New HPOP, 3 new injectors, new seals on others, new fuel pressure regulator, new fuel pump, sending unit mod to eliminate filters. 733 HPOP pressure, 65 fuel pressure at idle. Truck runs out of fuel pressure after its warmed up and driven about 20 miles. Haven't checked voltage at pump while driving. I had taken it to a seasoned tech of 20 years and he had replaced HPOP and 2 injectors and it does start better but problem is still there.

We have a 99 Suburban LT 5.7 V8 4x4 with 210K miles. My wife was driving the vehicle the other day and while at a stop light the oil pressure got very low approximately 20psi according to the gauge. I need to find the oil pressure sensor location to check the true pressure using a pressure gauge but I can't seem to find it. From what I've read it should be by the oil filter or by the distributor cap or on the underside of the engine. It's neither around the oil filter or the distributor (using a mirror looking everywhere) nor on the underside of the engine.
What I have found is two sensors. A sensor I believe by #1 and #3 spark plug (driver's side) screwed into the block and a sensor on the passenger side of the engine (screwed into the block) accessed from underneath the vehicle. The sensor on the driver's side of the vehicle appears to be the best candidate however neither of the sensors looks like the replacement part when I view the picture of the sensor online.

The battery in my 2007 Honda CR-V keeps dying approximately every 2-3 weeks. There is no electric at all; I can't use the key fob to open the car, etc. When I jump the car, it is completely fine for about 2-3 weeks and then it just randomly dies again. It always dies at the same time/place - in my garage sometime during the night. I have never had it die anywhere else or at any other time. When it first happened I took it to one mechanic who told me the battery was dying. So, I replaced the battery (this was within the last 3 months).
Then 2 weeks later the car died again. I took it to a different mechanic and they tested the battery and alternator and said they were both fine. They said the battery coils were loose so they tightened them and said I should not have any further problems. Two weeks later the car died again. I called the same mechanic back and said it died again. They told me they fully tested the battery and alternator, and everything in the car looked find so what was causing this.
They suggested that perhaps there is a light on somewhere - like the glove box - and I just don't realize it. I checked and there is no light in my glove box so that can't be the problem. I thought perhaps it was because it was winter, but now the weather is in the 40s and 50s and it just died again two nights ago. I really don't know what to do since the mechanics I have gone to say everything is fine with the car.

There is only one thing I don't like about our new SF. The transmission shifts from 4th to 5th gear at approximately 60 km/hr (36 mph +/-) and the rpm's drop to 1500 rpm. Now, when I want to speed up a tad (which is a frequent occurrence when driving around town), there is a pronounced hesitation before it drops back into 4th gear and accelerates.
In 5th gear at 1500 revs, I find that the engine is 'lugging' a bit. Yesterday, I started to compensate for this by changing to manual shifting as soon as the trannie shifted into 4th gear and leaving it there when I was traveling in that 60 kph speed area. For me, this is MUCH better and I quite like doing some of the shifting any way since I spent so many years driving manual transmission equipped cars.
How have others found the car to be when driving around town? Other than that, I really enjoy this car. Easily the most comfortable seats of any car I've ever owned --- their design provides terrific lumbar support and the new cloth material has a great 'feel' to it.

Over the past few days I've noticed a clicking sound that occurs when I reach approximately 80 mph. At first I thought the clicking may be coming from somewhere in the dash, but I had my wife listen while I drove and it seems to be coming from near the gas pedal. When I decelerate to about 70, it goes away. The faster I go above 80 mph, the faster the clicking.

I have a '05 Honda odyssey that has recently started showing drop in rpms at approx 30MPH. At that speed, I see that RPM suddenly drops from 2500 to 2000, pressing on gas really hard, triggers downshifting of gears and everything comes back to normal. I suspect some issues with how gears are being shifted...

I have a 2004 Toureg with approximately 31000 miles. Initially the noise Whining/ Squealing - sounds like a bad belt - would occur at approximately 40 mph and continue through the drive but if I dropped down to 30-35 mph it would stop. This would happen sporadically. Now it is occuring about every time I drive. I have had it in the VW Dealer twice and they are unable to detect the problem .

What the heat losses are approximately kwh from the transmission and inverter are. I understand this will vary with speed and driving conditions but reasonable estimate will do.

My wife was recently driving our 2007 Honda Odyssey on the highway at approximately 60mph when the van suddenly and significantly decelerated. It did this while my wife had her foot on the accelerator and without her activating the brakes. It occured twice in quick succession and then the van returned to normal operation. She did not notice an increase in rpms or hear any loud noises. After this happened, I took the van to the local Honda dealer and they could not find anything wrong with the vehicle. They made an educated guess that it might be the beginning signs of a transmission failure. The van has 72000 miles on it. I am concerned about the safety implications if this were to happen again...

My 06 Mitsubishi Galant's A/C quits blowing air after approximately 50 miles of driving. The fan is running normally but the ducts don't have much air coming from them. I let the car set for a period of time and it starts working again. It acts like the coils are freezing up. I had a mechanic check it, the freon is ok, there is no cabin filter and they replaced a relay hoping to fix it. So far, no luck.

What is the meaning of the persistent warning beeps that occur approximately every minute? The warning beeps began after the car was turned off following a 200 mile trip and are still occurring now. No warning light ever came on. How do I stop them?

I have a 2010 S with 70,000 miles. At 60,000 miles, just after the warranty ran out on me, I started to get a gear grinding noise for approximately one second immediately following a cold startup. It doesn't happen all the time, but I'd say once out of every eight starts on cold mornings after it's been sitting. I researched the issue pretty extensively and it seems to narrow down to the cam timing gear being the issue or a bad starter relay. The 2009's had a TSB for the issue being a cam timing gear, but the dealer assures me that my vehicle is not one of the ones covered by the TSB.
I'm inclined to try the relay fix, since a new relay is only $60. The thing is, I would hate to install the part and find out that the issue remains and then be out $60. Any identical relay elsewhere in the car that I can swap it with to see if that work. Of course, if the relay is bad, I'd be breaking something else possibly. Or, even better, is there a way to test the relay to see if is the cause of the problem?
