Question about Cars & Trucks

1 Answer

I have a Craftsman 3 gal air compressor--model #921.153101. I replaced a defected coupler, quick connect. When I got everything reconnected and turned it on, pressure rose beyond the normal cut off

And continued to rise until it almost reached the red zone on the gauge.I turned it off, released all the air, and then tried it again. The same result. Is there something I might have tightened or bumped in the process which is affecting the pressure build up?

1989 deville load level compressor runs for 3 seconds then stops after turning ignition switch on


Check and make sure that the level control lever that goes to your shocks was reconnected. Might have been overlooked....Hope this helps.

My ac clutch will not engage on my 1999 ford expedition


It sounds like it's either out of freon, or compressor oil. You can pick up a can of refrigerant that has the oil in with it at any Autozone or Advance Auto. It'll have the pressure gauge and fill hose with a coupler already on it. Hook it up with the engine running and a/c turned on...compressor should kick on pretty quickly. Hope this does the trick for ya!

The air conditioning in my 2005 T&C stopped working. Right before it stopped there was a "burnt" smell coming through the vents. What happened?


No air coming from air conditioning vents
  1. Check the air conditioner fuse and replace as necessary.
  2. Air conditioner system discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
  3. Air conditioner low pressure switch defective. Replace switch.
  4. Air conditioner fan resistor pack defective. Replace resistor pack.
  5. Loose connection, broken wiring or defective air conditioner relay in air conditioning electrical circuit. Repair wiring or replace relay as necessary. Air conditioner has a smell when used
    1. The air conditioner evaporator drain hose is blocked or partially restricted, allowing condensation to build up around the evaporator and drainage tray. Clear the drain hose where it exits the passenger compartment.
    2. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

The air ride stop working


There are a few things that happen most often on these vehicles. Air suspension compressor failure,A/S relay and a small coupler under the master cyl breaks. Listen to see if the compressor runs if it does check the air line coupler under the M/C to see if its broken,if not it,its possible the compressor motor is ok but the cylinder is worn and not producing pressure,you can check this by removing the air line on the compressor and checking the airflow out of the line(it should be significant). If it is it could have a leaking air bag also

Where is the a.i.r. pump located



The air pump for the secondary air system (emission control device) is located under the battery. If you do replace it, replace the check valve too, it is on top of the exhaust manifold and connected to the pump with a hose. The check valve fails and ruins the pump. Source(s): http://repairpal.com/volvo-850-1997/comm…

http://repairpal.com/air-pump

OR


I think they are talking about the pump to provide vacuum to the climate control when the turbo is putting boost in the intake manifold. The vacuum can come from an electric pump or from an engine driven pump, something like an old engine driven fuel pump. I needed an electric pump for my 765T, and all the wrecking yards wanted to sell me the engine driven form. (A new one was $500, and it wasn't that important to me.)

An engine that takes the engine driven pump will have a hole in it while the others will not have a hole. Source(s): 35 years maintaining my own cars, including 17 years with a 1985 765T

The air compressor will build air to 45 psi but no futher and regulator is also at 45 psi and no higher and has been running for over4 hours this is a single stage 4 horse 18 gal craftsman modle 919-16418...


when the compressor is running do you hear air blowing off? If so, check the manual blow off valve to see if it stuk open. The regulator controls the pressure check it for leaks

How does one reconnect the air suspension


You probably have a leak in the system. Did "they" check the lines and air suspension? "They" probably disconnected the compressor to keep it from burning out from overuse. You need to fix the leak before reconnecting or the compressor will wear out very quickly.
