    IThankyou for your replies so far, I know that there is a known fault with the resister located on the side of the heater box but when faulty this stops the blower working on all speeds bar full. This works fine, the problem is that I am only getting cold air from the blower in the cab, there appears to be hot water supply from the engine going to one of the pipes that goes through the bulkhead from the engine compartment but it remains cold on the exit pipe from the heater matrix. I have been told that there is an electric valve that opens to allow the water through and that it may be in the cab under the dash somewhere, before I reduce my car to a box of bits and a mornings worth of cussing I just wondered if someone could confirm? Thanks in anticipation. T

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

SOURCE: running fine then wont'nt start

You will have to pull a spark plug out to check that you have spark when cranking the engine,while you have the plug/s out do a compression test to determine health of engine and wether it is in fact giving compression,eliminates other potential faults if compression is good.If you have compression(around 140 ish)and introduced fuel and it wont fire up it only leaves electrics as the fault.3 major engine requirements to run Fuel,Compression,ignition.When checking spark at night is best as you can easily see wether you have the correct type of spark,Blue and if its quite you will hear the spark as well.Your fault is consistant with ignition module,coil or lack of power to ignition.Faulty modules will give a spark but its too weak to ignite fuel and the spark will be yellow in color.Let me know how it goes.Good luck

SOURCE: MISFIRING ON CYLINDER 1 VW POLO 1.4 3CYLINDER

I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

Locating the heat actuator for my 1999 Cadillac catera blows only cold air on drivers side


For each side of the vehicle, there is an air mixing valve buried inside the dash and controlled by an electric actuator. This can be a very complicated problem because the HVAC control system in this car is complicated. First step would be to use a code scanner to see if any error codes (DTC's) are set and proceed from there. If codes are set, you can try disconnecting the negative lead on the battery and then reconnecting it a few minutes later. If that doesn't work, determining the problem and fixing it is a job for a dealership.

The heater corps in my truck went out


To replace the heater core in that model truck you will need to remove the whole dash, steering colum. Then discharge the A/C and remove the heater/a/c case. It is a time consuming job and difficult without the proper tools and info. If you are going to attempt this then be sure to disable the air bag system by disconnecting the battery for at least 10 min. before you start working. Good Luck

1998 explorer -Only hot air due to broken hot/cold air partition.


Removing the dash is depending on your mechanical skills not that difficult. You have to disconnect the outside evaporator case from the firewall to gain acces to the heater case attaching nuts. I believe the only way to get the door is the complete heater case. If you are not comfortable removing a dash,have a professional do the job
