Question about 1999 Ford Taurus

1999 Taurus. A/C issues

At high rpms 2.5 + driving around 70mph, the compressor stops working. I just had the refrigerant charged as well and the pressure is good. The first time this happened, there was smoke from the vents. I checked the heater coil and found no leaks also.

    Thank you for your response. I got in and took a good look at it this weekend and found that the A/C compressor clutch was shot. The smoke was from the clutch, and I found metal shavings all over.

03 taurus ac works at low rpm only


Well, YES, NO, and SORT-OF???

Your refrigerant evacuating and and recharging skills might be helpful, however, you cannot capture the R-134A refrigerant using the same equipment that you use on refrigerators unless you have empty refrigerant tanks to use. The refrigerants are not compatible with each other.

Then, yes, it is possible that your A/C clutch is slipping. You can verify this by listening to the sound of the compressor. You can usually hear the clutch making a grinding sound. There will usually also be a bunch of rusty-looking dust around the area of the clutch due to the metal tearing off of the clutch surfaces.

Then you need to decide if you want to replace the clutch assembly or the entire compressor. If the clutch assembly is all you need, then it can be replaced without any type of refrigerant recovery needed. It is also a whole lot cheaper to replace than the compressor (see picture and link below).
However, the clutch can be pretty tough to replace without the special tools needed - especially if you have never done one before.

AC does not work. Compressor will not engage Blower only blows on high speed. Is the two a related problem? Where should I look to solve the problem


The most common reason for the compressor not engaging is low refrigerant pressure. The ac system has a safety switch that will not allow the compressor to engage when there is not enough refrigerant pressure because the the refrigerant carries the compressor lubricant throughout the system. Have the system checked for proper charge. You probably have a leak. The fan is probably a separate issue.

A c starts off cooling good then compressor starts kicking in and


Several possible causes. Knowing the state of refrigerant charge would be helpful. Assuming it has a 'full' charge (full charge 680 Grams = 1.50 Pounds) Most common causes of AC problems:
1. Thermostatic switch (sensor) malfunction in the evaporator - allowing the evaporator to ice up. Check the vent temperature (using a cooking thermometer) to see if the temperature gets near or below freezing (32 Deg F.). If so, the thermostatic switch in the evaporator is defective. Replace it.
2. Refrigerant UNDER-charge. If the temperature does NOT get near freezing, then you need a set of AC gauges to check the compressor head pressure (High side) and the suction (Low side). High side pressure (nominal) is 229 PSI (+ - 20 psi) @ 2000 RPM. Low side (nominal) is around 20 to 40 psi. NOT common problems:
1. The magnetic clutch coil on the compressor... as it heats/warms up, the coil windings could be going 'open" circuit which would turn the compressor 'off.'
2. Compressor inefficiency (worn out).
3. Expansion Valve
4. Clogged Condensor

2003 Ford Taurus wants to die when coming to a stop


TRY THIS AND LET ME KNOW IF IT CORRECTS YOUR PROBLEM
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

No Heat in 99 Taurus


Just finished fixing my daughters 1999 taurus heat. It would blow warm only when running down the road. At idle it blew cold. I started with replacing thermostat, and water pump because they are the easier fix. Still did not help. Then I replaced the heater core. A daunting job but not that hard to move the dash slighly out of the way to replace. There is a good write up at tarusclub.com. After that, heat was better but at idle, it would still blow cool sometimes. Researched and found answer. Park car on the steepest hill you can find with front of car up. Start car and take off reservoir cap. Let car warm up and keep rpms about 1500. After a while the fluid will come running out of the car and all over the place but it will bring air bubbles with it. Reduce rpm, add more fluid and repeat about 3 times. It will make a mess but after that, the heater works perfectly. We get heat long before the temp gage indicates any and it never blows cold unless you lower the temp.
