SOURCE: SUSPENSION AIR BAGS WON'T INFLATE ON 1998 FORD WINDSTAR

I would recommend going to strutmasters.com and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. Airbags and compressors are constantly having to be replaced. Also something alot of people don't know is that theses air suspensions are not meant to be in temperatures above 90 Degrees or below 40 Degrees. That is most of the world. The temperature will cause you to replace alot of bags. and typically when your replacing a bag you are going to have to replace the compressor to because the bag had a hole or small crack in it causing the compressor to over work and it will die. I posted the link below so you can take a look

I hope I was of some help

Good Luck!!!

SOURCE: Air bags suspension won't inflat. Checked all fuses & air suspension switch. What can the problem be?

Probably failed seal or air bag leaking air. Check again and try to see if this will do the trick. Sometimes pvc line could fail to deliver air to the bag too!

Air Suspension ??????

Air Suspension Description and Operation
Air Suspension
The primary mission of the Air Suspension System is the following for the rear suspension under loaded and unloaded conditions:
• Keep the vehicle visually level
• Provide optimal headlight aiming
• Maintain optimal ride height
The Air Suspension System consists of the following items:
• Air suspension compressor assembly
• Air suspension sensors
• Rear air springs
Important: The Air Suspension System must have a voltage supply of at least 12.6V to operate properly.
The Air Suspension System will maintain the rear D height within 4 mm (0.15 in) in all loading conditions and the leveling function will deactivate if the vehicle is overloaded. The side to side D height variation is maintained within 8 mm (0.31 in). After ignition is turned off, the air suspension control module (ASCM) will remain active for between 30 minutes and 2 1/2 hours. The system will exhaust pressure within 30 minutes after the ignition is turned off to lower the vehicle after unloading. In a temperature-controlled environment, the leakage of the complete load leveling system will not result in more than 1.4 mm (0.05 in) drop of rear suspension height at GVWR during a 24 hour period. If the outdoor temperature drops from +20°C (+68°F) to -5°C (+23°F), the rear D height may drop as much as 25 mm (1 in). However, the Air Suspension System should return to the specified D height when the ignition is again cycled to ON.

What is the problem ?

Diagnostic Trouble Code (DTC) Displaying
The Air Suspension system has an internal clock to prevent overheating if the compressor assembly is running for a prolonged period of time. If the system overheats, all leveling function stops until the system cools down. During this time, the indicator LED on the air inflator switch will be quickly flashing at a constant rate.
The other three diagnostic trouble codes are displayed with a blink code on the inflator switch LED. The Air Suspension Compressor Assembly shall begin to indicate the code when the condition to cause the code becomes current.
The number of the fault code shall be represented by the number of flashing pulses on the inflator switch LED. The flashing pulses shall have a repetition rate of 0.5 seconds and each code shall be separated by a 3.0 second delay. All codes shall be flashed in the order of occurrence of the fault. The blink code shall take priority over other processes that have access to the inflator switch LED. Refer to the following:
• DTC 001
• DTC 002
• DTC 003

Rear Air Suspension won't air up


take the sensor arm loose and manually operate it, when it is up, it thinks the suspension is low. Spray the bags and hoses with soapy water to find any leaks, dawn dish detergent works well. repair any leaks. If no leaks manifest, take a hose loose and see if you are actually getting air pressure from the air pump. Just because it is running, doesn't mean it is supplying pressure.

Why won't rear end raise up ?


I have a 2000 Lincoln Town car, had the same problem, it was the rear air suspension/shocks. They are air bags basically that levels your car and it cost about $300.00 for each at the dealer for parts and install but it also has its own motor that inflates and deflates these air bags and I also had to replace that and that cost over $400.00 installed at the dealer.

Save your self the hassle and expence of troubleshooting and replacement parts, install a suspension retrofit kit which changes the rear bags to coil springs and the front to struts. A car this old you might as well start over for less than $500.00......

1999 Eldorado rear air suspension inflated to max


Converting from the air ride suspension to the passive coil spring suspension will eliminate this problem. To fix your air system you will have to purchase the parts directly from the dealer which means the prices will be severely inflated. Check out Strutmasters website at: http://www.strutmasters.com/Cadillac-Eldorado-Air-Suspension-Rear-Conversion-R-p/-cad-r5ns-el.htm My Uncle converted his Cadillac Deville two years and has only had positive things to say about the effects! I hope this advice was of some help.
