Re: Thermal Expansion Valve TXV Location

Just got back from the dealers. I walked in and told them to check the tvx and compressor. They found the A/C was low on gas, so they refilled it to the correct weight. They claim low gas can cause piping vibration to the tvx. Car is 8 weeks old and even from factory low on gas can be common.

Touch wood all is good, will report back in a week or so if the problem persist. So far on the drive to work from the dealer was all good. My A/C is also noticeably cooler...

I spoke too soon, on the way home from the office, the noise returned, faintly though. Immediately booked it in again for the 5th March.

Yes, that is what I would like them to do, but as like all other doctors - the dealer mechanics will need their own diagnosis before yours. So hopefully in March when the car is in for the whole day, they will have a firm diagnostics.. Mind you, no parts will be changed at the next one, only diagnostics..

The A/C regas has lessen the noise for sure, so A/C is definitely the correct place to hunt.

Hi imaz, Make sure your dealer has a new compressor ready to go in. Mine was in and out of the dealership for 6 months until they finallly replaced the compressor that caused a great deal of upset. Save yourself months of anxiety and insist the compressors replaced next week. Good luck mate.

The compressor change out took half a day. They already diagnosed a low gas on yours from the pressure gauges. The gauges are used during the regas process therefore there is nonthing else to diagnose. A faulty TXV would have shown up on the gauges prior to the regas therefore your pressures are within tolerance· Trust me, demand a compressor change.

Thanks, will give them a call tomorrow and possibly get it in even earlier than March.

How should I proceed for the demand? I guess there is no other components to test for the AC itself...

Also did they replace your compressor with a NEW from the "spares" department, or wait for Chrysler to ship out a refurb unit out of US from the Warranty department?

Update - Booked in for the 25th Feb Monday. Will take the whole day for diagnostics. - I will take the day off.

Re: Thermal Expansion Valve TXV Location

Diagnosis should take around 15 minutes. (Can only be done off gauges). The compressor fitted to mine was new straight out of Melbourne. Took a day to get here. If your dealer is reasonable, ask him to contact the Service Manager at Albion who was very helpful with mine.

Its gonna be a long winded road.. I will bring it up though next week, thanks. - You wouldnt remember the name of the service manager?

The fact the car was on gauges already, surely they would have suspected something with the compressor upon refilling. Beats me though why the car was low on gas.. maybe a leak or something?

Re: Thermal Expansion Valve TXV Location

Sure Mate. I don't think he'll mind, his name is Craig....very helpful. I took mine to an accredited AC expert within the 8 months I had the problem and he let gas out bit by bit, using the gauges, observing the compressor kick in then turn off as the high pressure switch did it's job. If the TXV was faulty, or any type of blockage in the dryer or condensor, I was told the pressures would be right out of tolerance....but they were not. Letting gas out quitened down the groan but it was still there. He pointed out that the compressor claimed to have been replaced by Jeep was in fact the original one....dirty threads where the hoses are fixed to the compressor gave it away... Once I raised this with Jeep, the compressor was replaced and no noises since. Your dealer will tell you within 30 seconds if it's the TXV....that how long it takes to hook up the gauges and turn on the AC. Keep us posted how you go. There are a few with the same issue being reported around town.

Are you saying your compressor has previously been claimed to have been "replaced" but were not? Sorry, kind of lost me there. Heck, I will mark my compressor with a scorer.
