Replying to: jade4 (Nov 19, 2008 6:09 pm) Heat Fixed!! Ok after replacing the CCM electrical power was restored to the Heat pump motor. But only had heat at left Vent. I figured there was something blocking the coolant. I removed the hose from the motor going into the heater core. I blew air through the hose. At first the air wouldn't blow through it. Finally it did. This is a main problem. make sure that when you get your car serviced anywhere that they do not mix the Anti freeze. It will make a Jel and block the core. I know there are places that sell the Green antifreeze that is supposedly compatible. Don't do it it won't mix. I hope all the stuff I have done will help others with their heat problems. Jade4 I did find a used Pump on the internet for $138.00 Dollars. My old pump still works but the contacts in the motor are worn down along with the contact on the windings. I will see if a local electric motor repair shop can rebuild it. Will let you all know if this is something that can be done to reduce the cost of buying used or new ones. Anyway <<<<< Happy in Tennessee now!!!!
#9 of 12 1994 XJ6 Air Conditioning Problem by OME_OMY Dec 11, 2008 (12:06 pm)
Tried freon only with local general shops, slow leak. but looks like i am headed for major air conditioning work in the spring. Anyone out here have the problem of the air conditioning working, but not ever cooling very well. Max button doesn't do anything. This A/C has been weak since buying it several years ago. Freon loss isn't the problem. I hate the prospect of new compressor, dryer, etc.   And what drives me crazy, is that when i turn the switch on, the A/C comes on when it wants to, about half the time. And when it is hot here in Louisiana, we NEED A/C. Seems like an intermittent switch. Here we go again with electrical problems.
#10 of 12 Looking for a great Jaguar mechanic/tech by OME_OMY Dec 11, 2008 (12:23 pm)
My search is focused on looking for a good or great Jaguar mechanic/tech. Particularly electrical/computer problems and enhancements. My experience with the Mobile Alabama Jaguar dealership and others is that...The techs that are great for newer models are not old enough to be great with my era Jaguars...1994 XJ6   I will travel long distance to any southern states particularly to find such a tech and service facility. Texas, Louisiana, Mississippi, Alabama, Florida, Tennessee, Missouri, Arkansas for example. Do YOU know one?
#11 of 12 Auxiliary heater pump failure by Ronmay Dec 24, 2008 (1:02 pm)
My heater pump failed a few months ago. I tried finding a used pump, but they wanted $300 for a used one. I finally tore down the pump and rebuilt it myself. If the armature isn't too chewed up, just dress it down woth sandpaper. If it's too bad, have it turned at a shop. I found new brushes(slightly oversize) at Stine lumber for $6. I had to cut them down slightly with a file, but that was easy on graphite brushes. Make sure none of the segments on the armature commutator are shorted. run a thin piece of metal down each groove to remove any trash. Total cost of the job: $6.54. Ronmay

Replying to: jade4 (Oct 29, 2008 1:27 pm) Belive it or not it is likely the fan motor (blower motor)in the car.If it is going bad the blower motor will stick on air or heat ...........wich ever u used last.
