Tin top Aircon - Seized Compressor?
Well i guess it had to happen some time, the trusty tintop is limping.
Firsty; what do i need to do as part of getting its replaced and the car on the road.
- Just get it swaped it for a replacment from a breakers and leaving it plugged just using it as a idler pulley
- Swap it out, but get it re gassed and hope for the best.
- Get new oil put in with the gas?
- Get the system flushed?
- Have a new rec/dryer?
- Have a new condensor?
Secondly; why has it failed, is it likely to do it again, was the garage as fault (see below)
On the way out of work I smell burning and fairly quickly come to the conclusion it was me, stopped and looked under the bonnet and the a/c clutch is
a dully red colour and smoking violently. Compressor is seized and the clutch is slipping so unpluged the binary switch to stop it engaging and put it
in mind to repair it at my lesure.
However a three hour drive to bristol friday night rapidly highlighted that the bearings didnt like being a dull red colour, and now that its done
another 300miles, its very clearly doesnt have another 300 in it given the noise&heat its giving off.
Three weeks ago it worked ok (not sure how cold, as it wasnt summer, but kept the windows clear, etc) and stopped fairly suddenly, highlighted by a
shushing noise from the heaterbox (expander/evaporator) when turned on. So had it checked over on thursday which resulted in a verdict of no leaks,
but in need of a re-gas. Two 10min runs later (during which is all worked a treat) its fails as above.
Not aiming to point fingars, just learn from whats happened get it fixed.
Have already bought what i hope to be a replacment compressor, another Sanden SD7V16 which appears idenitcal but is a slightly diffrent model number
as its off a of a similar aged xsara rather than a 1.8xu 306. This whats on there current Peugeot 306 Air Con Compressor Pump

They used to throw thier conrods but that was the old reciprocating type dont know if they still use those.
Certainly change the pump, a new drier, vac out and regas/oil will solve it you wont need to change anything else.

When mine went wrong I took it to the local guys who fix the chiller units on freezer vans.
It's the same technology and because they are dealing with commercial customers who expect rapid repairs and don't want to pay through the
nose for it they charge sensible rates.
Worth a try especailly as buying that sort of thing second-hand always carries the risk it won't last.
HTH.

I bought a second hand one for £30 and it's worked so far. When I had it charged up the mechanic asked what had gone wrong with the first on and
when I told him it had seized he put a double dose of lubricant in. The one in mine had 5 double acting pistons and worked like a pressure washer pump
but it was well stuck and I had to knock one of the pistons out with a hammer.

Hi, sorry for the delayed reply. I cant get on at work and dont appear so where viewing on my phone. Thanks for the thoughts and comments.
I spent today in bed feeling like death and as i need the car tomorrow it ended going back to the garage who did the work origanally who fitted the
replacment pump and have had it running for two hours in there yard without issue yet (touch wood) cost £60 in labour to change the pump, free regas
as the gas was still in it. So not ideal, but assuming it noe works without complication it can go down at one of those things. If it fails again, it
will be going back, and some more firm negotiations will be taking place. I told them to put plenty of oil in it, so we shall see!
