do you have a website for them?

Do you still have A/C Amps for a 1986 XJ6??? If so cost please?

A/C Amps
 

Yes I have several right now the cost is $200.00
All are pretested and calibrated.

Guess I just noticed your message, sorry.
Yes I can ship to The Netherlands. Price for unit is $200.00 US and whatever shipping costs me would be added. I would find most economical shipping available

Does anyone know of where I can get a replacement cabin Temp. sensor. I thought it could be worth a shot if its not to expensive, to replace it and see if there are any changes for the better.

there are 2 cabin / air sensors. Which one? Those things rarely go bad.

what year model car?

sorry, '85 xj6 series III. just looking for ideas as to why when the temp is set at 65 the air works for a while then switches to heat. I got another amp for it ,not new , so maybe that's defective too. had no idea there were two sensors.

there is one cabin air temp sensor at the dash overlap above the center vent grille.

there is a second incoming air temp sensor at the passenger side floor rise ( as the floor becomes the firewall / bulkhead), and it is screwed to the right corner in a little circuit board. This one becomes covered in grime from incoming air. Take a used toothbrush, remove it and gently clean it.

Most likely the problem is the amplifier, the symptom you describe is typical of a failed amplifier. Easiest way is to substitutte the amplifier with a known good one.
However, I have a theory that it could also be the overpressure switch in the
compressor cutting it off especially if you are using R134a refrigerant which works under higher pressure and if the compressor is designed for R12, there is a pressure conflict.

Isn't the GM A6 supposed to work using both R12 and R134? Is the overpressure switch you are referring to the superheat switch or the HSLP switch?

some Harrisons work with both refrigerants, those built after 1992 when R134 came out. But remember these compressors were in use since the 1970s with R12 only. The label in yours does not say R134a.

the switch I refer to is the one at the back of the compressor, some call it super heat, some call it over pressure. It blows up the same way.

there is a new redesigned Harrison compressor which is lighter and more efficient with R134a. Rebuilt compressors always fai1l just like alternators.

State governments still use R12 in fleets and R12 is still made in Mexico and Brasil by Dupont. If you want R12, go to a State Diesel Tech College and ask the students to fix your a/c.

Thanks Jose, I'll start with the sensors, make sure there clean. Not sure what type of refrigerant is in mine. another thing to check. Also, if BEARING 1
is listening I may be in the market for one of those amps you've made. Need to get contact info. Thanks again guys

Jose, How does one identify this new Harrison Compressor. Do you have a part number/source of supply? I need to change mine as it whines terribly in direct relationship to engine RPM. It's louder than the engine at highway speeds and does a lousy job of cooling.

iramphal,
the new Harrisons are sold by www.retroair.com

talk to Rock Browning the owner, great guy for advice and support.

Retroair seem to be defunct. The compressor you're referring to, Jose, is this one correct?

yea that is the compressor.
I tried to open the retro air page and no luck. Maybe he forgot to pay the domain address!

The one thing to note is that the RockAuto A6 has the HSLP (High Side Low Pressure) switch setup, but may not include the switch itself. If your A6 is already setup with the HSLP switch you will have to take it off the current A6 and install it on the new one. No big deal. If you are currently setup for the Superheat switch there's other things that need to be done on the wiring. I've seen posts on how to do that, but you'll have to find another source other than me for that.

This is an old post but are you still making these amplifiers? I'm interested if you are. Thanks

Hello. Yes, I still make the Jaguar AC amplifier and have some in stock.
Fully calibrated and ready to plug in.

Need more info on how to purchase one . Have an 85 jaguar xj6.

Just found this thread... @Bearing1 are you still doing the AC amps CAC45402?
