blower relay located on the engine compartment by the firewall
can the fuel injectors on a 1994 grand marquis be checked without removing them from the engine, if so what type of instrument do i use
get fan clutch checked may be blowing air but not enough
I have a 2002 Mercury Grand Marquis LS and the air conditioner motor stop blowing. The compressor seems to be getting cold. I have checked the fuses and relays, still did not help. Any help will be greatly appreciated. Thanks, Jackson I have the same issue. Started Sept 2008 - seems like a MFG issue. Anyone else want to add to this? ... thanks ... Angel The motor control unit on these cars (GrandMarq/CrnVic from FoMoCo) is sub par quality and require replacing too often. The MCU is a small circuit board type plug in that is on the firewall near the AC hoses as they enter the passenger compartment. Easy to med difficulty in replacing. I have a 2002 GM LSE that I had to replace the MCU. Dealer only part - $30 - $60.
It really needs to be checked out but it probably is the blower votor.
Could be the caliper or the metal line. You will have to have it checked.
Have you checked the coil's ?
Blown fuse? Freon leak? Suggest you take it and have it checked to be sure.
There is a problem, and because this is a complex system with many possible causes it needs to be checked by a knowledgeable person.
Chances are your air conditioner is low or out of coolant. You can go to AutoZone, Napa, Advance Auto, or numerous other do it yourself car repair stores and have it checked out.
The light indicates a problem with the air bag system. The system should be checked, as the bag may not properly work in an accident.
The first thing to check is that the outside unit is running. That the compressor and the Fan is running. If they are running, then have the Freon pressure in the system checked. You may be low on coolant.
With a 4.6 L engine, on the hi-way, you should get around 28 MPG. Have the injectors checked, timing, and sensors.
