In June of 2005 I replaced the Wranglers, that Ford put on my 99 Explorer XLT when they swaped out my Firestones, with Michelin Cross Terrain 235 75R 15's. Although the Wranglers were on the truck for 59K, I did not realize how awful their ride and handling were until I started driving on the Cross Terrain's. I purchased the Michelins at Costco. Got a very fair price that included everything plus a 6 year road hazard warranty. They even filled the tires with nitrogen gas instead of compressed air. When they mounted the tires they used a torque wrench to set the lug nuts. That really impressed me. Been back to Costco once to have the tires rotated, re-balanced and pressure adjusted. All this part of the purchase warranty. I know that tires and service are a very subjective things to talk about. But I am very impressed with the Michelins and the service at Costco.
#5167 of 6400 Hot air from vents
Jul 13, 2006 (3:29 pm)
My 2002 Explorer started to blow hot air through some vents and cold air through others. My mechanic says this is a protection mechanism when the AC system is low on gas. Never heard this before, is this correct?

02 limited...when in auto the lights always come on. where is the sensor located? is there anything i can do to try to fix it myself? any idea on cost to fix? at this point unless i can fix it myself, i'll justuse them like regular lights, or maybe just leave them on all the time. any help is appreciated

Hello I have a 2006 Eddie Bauer 4X4 Explorer. Tonight after eating dinner with the family it seemed like the steering wheel was looser than usual. At low speeds I could feel a vibration in the wheel at certain points. I do not know if there is something wrong with the wheel or should the wheel be loose like this. I was wondering if anyone else had this problem or if anyone knows what to do about it? Any help would be great.

A 2006 is too new to work on it yourself. Should not that be covered under warranty? Did you take it to the dealer, and if so, what did he have to say?
#5171 of 6400 '96 Explorer A/C Question
Jul 15, 2006 (7:48 am)
The A/C on my wife's '96 Explorer was not cooling as well as it used to. I also noticed that the compressor clutch seems to be engaging and disengaging much more frequently than I would expect...every 5 to 10 seconds or so. My mechanic added some refrigerant, said there were no major leaks, and did not comment on the compressor engaging/ disengaging. The A/C is working well now, but I noticed there is no change with the compressor clutch is still engaging/ disengaging as frequently as it did before. Is that normal on this truck? If no, what is likely wrong? Is it something I should have repaired, or not worry about it? The truck has 112K miles on it, but for the past few years has been driven only 2000-3000 miles per year. My wife uses the truck mostly as an inclement weather alternative to her sports car.

I have not taken it in yet, I am going to drive it later and see if it happens again, but if it keeps up I will bring it in on Tuesday. I heard that it may be that the wheels are not properly alligned,causing a vibration in the wheel. Otherwise I love my new Explorer.

Any particular Air Conditioning system in any particular state will operate slightly differently under different conditions of Ambient Heat, and Heat Load. You did not give any specifics regarding the conditions that you were operating the system at before and after the repair. To create an equal analysis, the test conditions must be the same before and after the work is done, so that we are not comparing apples to oranges. You state that before, it was not cooling as well as it used to. You state that now it is cooling well, but the clutch cycles often. The comparison has to be made under the same conditions, approximately same hot weather, in the hot sun, and very important that you set the AC system to MAX COOL with the FAN on HIGH BLOWER each time you test. If you had the AC at a lower fan speed, it will place a lower heat load on the system, and the compressor will cycle more often, which is normal. Understand that the system does not operate under the same heat load all the time. Once the inside of the car cools down and the compressor can easily cool the car, the pressures in the system drop and the compressor will drop out sooner, and cycle more often. Lower temperatures = Lower Pressures = Compressor cycles out when pressure drops. The compressor cycles out when the pressure drops because it is operated by a low side pressure switch. When the evaporator pressure gets down to 21 to 20 lbs, the pressure switch shuts the compressor off, until the evaporator pressure rises back up to about 40 lbs, then it cuts the copressor back on. So TWO things cause the compressor to cycle off, Normal operation when the cooling is good enough for the pressure to drop to 21 lbs, or if the refrigerant charge is low and the pressure drops to 21 lbs. If cooling is not quite perfect and the compressor cycles on and off a lot, it might be that there could be a small restriction in the refrigeration circuit, usually at the orifice tube screen, which could cause evaporator pressure to drop and cut off the compressor. The mechanic can see this on his guages, by seeing that the low side pressure drops rapidly and quickly. If he charged it up, and watched the gauges, he probably desided it was working ok. I think in your case the AC is operating normally or near normally. Be sure to leave the FAN on HIGH Blower and the AC on MAX COOL (Recirculate), and see if the compressor still seems to cycle too often. If it is cooling well under all conditions, especially very hot weather, then the system is ok, even if it does cycle fairly often, it just means the compressor is doing it's job easily, and can rest more often. Let us know how does.
#5174 of 6400 99 Explorer Sport with bushing question
Jul 16, 2006 (12:13 pm)
Afternoon all (steve and tidester included!):
I have a 99 Ford Explorer Sport, 2wd, auto transmission. Put new tires on about a year ago and started having trouble (shimmy/shake from 62-68 mph, apprx) in April/May so I brought it in for wheel balancing. And again. And again. Still got the wicked shake, rattle and roll.
So, long story short, I brought it in to Goodyear (Goodyear tires) instead of the place that had been doing the balancing. Husband thought maybe a belt went in one or more tires. So yes, the back tires have to be replaced (they pro-rated the price, however). Also, Goodyear said that the front ball joints needed replacing (yah, after 145,000 miles, we agreed).
My problem came when I picked it up. I had a wicked bad shimmy, shake, shudder when I started to drive it away (in the front end). I immediately stopped the car in the middle of their parking lot and went back in. One service guy was at the desk and he said it was a common problem with Ford Explorers whenever they had to be lifted by control arm (to replace ball joints) and it had something to do with the bushing having to "reseat" and it would go away in 10-15 miles of driving. He apologized for not saying something to me.
Neither my husband or I had ever heard of it. Checked online, nothing popped up. I then called Ford and they suggested that I call my local dealership. I spoke with service rep there and she said she had never, ever heard of it either.
Goodyear claims it will all smooth out in 10-15 miles. I've now gone approx. 20 and yah, it is a tad smoother but I am still pretty suspicious. Every time I turn the wheels, the tires shudder. Has anyone else had this issue? Is Goodyear dreaming? Is my Ford dealer?

Many thanks for the detailed explaination. As you suggested, when I select Max Cool with the blower on the highest speed, the compressor is engaged 100% of the time. So it does appear that the system is functioning normally. When I place a lower heat load on the system, the compressor does cycle on and off every 10 seconds or so. I was thinking that it should be cycling on and off much less frequently (every minute or two), but it certainly sounds like you know what you are talking about. Thanks again for your help.
