Check engine light on secondary air pump not working. works with 12 volts but is it suppose to be less then 12 volts?

12 volts. there is a relay that supplies 12 volts to the pump when closed. this relay is in the power distribution box.

A/c is not working, was told it was a module or something on the heater box, would you know what they are talking about and how much to fix?

Without knowing any specifics, it sounds like it is the climate control box, which is a valve that diverts the air flow over the heater core to give you heat, then when you want air conditioning , a valve moves a baffle to divert the fan air to pass over the A/C evaporator coil located in the car cabin.

The bad news is all this climate control valves and mini radiators are underneath the dash and there is a lot of labor getting the stuff out, especially if it needs replaced. You might luck out and it is just a linkage rod became disconnected. But count on at least 500 bucks if there is disassembly needed

Where is the Secondary Air Injection Pump In a 2002 Merce4des C230 Kompressor Coupe located?

The Secondary Air pump is actually the Supercharger/Kompressor, the supercharger runs off the belt drive and the air is diverted through some valves for Secondary Injection. There actually is no pump on this engine. Quite clever design in my opinion. Hope that helps.

I have a 2002 BMW 745 I with 64000 miles on it. It passes emission smog test but gets 2 engine fail signals indicating a carbon buildup in the exhaust system. I have also had many intermitent erroneous...

I can only assume that your faults are for the secondary air system since they are common. The secondary air system comprises of an air pump, plastic lines, diverter valves, ports inside the heads and monitor by the o2 sensors. I recommend having the air pump tested for proper activation, a smoke test of the lines and diverter valves, and a scan to make sure no oxygen sensor faults are current. Clogged ports in the heads are possible, but I recommend checking the basics first.

Getting a code for smog pump

better check that info again. inspect belt routing diagram and vacuum diagram for thermactor pump and thermactor air system parts being present on your calibration. to my recollection there was no thermactor air used. where would they put all that plumbing?
pump, diverter valve, exhaust check valves, upstream and downstream air tubes? a ford has a label on the radiator support depicting the usage, hose color, and general vicinity in a schematic for ford technicians to identify. there is also a belt routing diagram that depicts the pulleys for the components. you dont have one...right?
you may have a code glossary for older vehicles. get the right manual at the library for free and restart diagnosis. or goto the emissions authorized repair facility and get the question answered after a quick self test

Where does the elctric air pump hose go and the two vaccum lines go

The electric air pump has two lines intake air and exhaust air the exhaust air goes to a diverter valve on some models then travels to metal tube and separates to the air check valves on the injection tubes to the exhaust manifolds. the diverter valve has the vacuum line on it which goes to the electric switching valve and then to manifold vacuum.

Suddenlt our vehicle driver side only blows cold air and the pasenger and rear vents blow the correct temperature setting.

You have a air box heater box air divert valve stuck you will need to replace it first start by looking under the dash passenger side you will see a round part with some vacuum hoses coming off from them start engine switch your location function switch see if working on divert er vacuum you most likely will have to replace your divert er valve.

2003 Grand Prix not blowing hot air. Does the heater coil need to be replaced? If so where is it located?

If the heater coil was bad, it would be leaking radiator fluid... probably into your dash/floorboard (depending on where it is installed in your model car). There is a switch that diverts the hot radiator fluid through the heater coil when you want heat. There is also an air diverter valve that helps to mix the hot and cold air. The fluid valve is controlled by the A/C settings control. The one that you use to choose between heater/air conditioner/vent/ defrost. The air diverter is controlled by the temp mixing controller. The most simple explanation is that one of those valves or the controller of one of those valves is not working. If the hot water cant be diverted through the heater coil, the coil can't exchange the heat (warming the air). If the air diverter (hot/cold controller) cant move to add heat, then all you will feel is air from the vent side (from outside) or from the A/C cooling the air.

I would guess that its either a controller or one of the valves themselves. Odds are, it is a controller. That tends to be what malfunctions first.

1998 328i.. Got a 1421 and 1423 code...not sure where to start...

1997 BMW 328I 2.8L Customer Concern: MIL is on with trouble codes P1421 and P1423, for incorrect secondary airflow on both cylinder banks. Tests/Procedures: 1. Perform a functional test of the Air Injection Reaction (AIR) system. Tee a vacuum gauge into the vacuum hose attached to the diverter valve, located on the cylinder head towards the front of the engine.

2. Allow the vehicle to sit over night. Start the engine (cold) while monitoring the amount of vacuum on the gauge at startup. At temperatures from -10 to 40 degrees Celsius, there should be at least 17 inches of vacuum. At the same time, the AIR pump should run and pump a large volume of air into the exhaust. Potential Causes: A.I.R. Pump
Air Pump Relay
Restricted Cylinder Head
Diverter Valve
Tech Tips: These codes are related to a problem detected in the Secondary Air Injection system. Scan tools with BMW software include a feature to command the AIR pump on and off. The pattern failures for these codes are the AIR pumps due to leaks in the diverter valve and moisture or condensation in the AIR pump.

Possible fix but not all items. Just areas to look at:
Confirmed Fix - A.I.R. Pump - A.I.R. Diverter - A.I.R. Pump, Air Injection Reaction Diverter (AIRD) Valve - Air Injection Reaction Diverter (AIRD) Valve - Check Valve, Secondary Air Pump - Diverter Valve Vacuum Lines
