Clutch will not disengage

johnsharpley on Tue August 26, 2008 12:47 PM User is offlineView users profile

Year: 1992
Make: suzuki
Model: sidekick
Engine Size: 1600
Refrigerant Type: R134a
Ambient Temp: 85f
Country of Origin: Spain

Can anyone help me, I purchased a A/C from AMA for my Suzuki sidekick 1600 EfI with power steering Part No 14404-4284 I am very pleased with the system it fitted really well with no problems. I took the Suzuki to a dealer here in Spain and had the system gassed up. it was pumped down for 30 mins and vacuum held for 15mins. a dye was put into the system and charged up with 680 grams of R134a. (24 oz). no leakes were found and air temp at vents at 2500 rpm with a ambient temp of 34C is about 14 C. I now notice that the clutch on compressor will not disengage, it will if I turn off the A/C switch or blower. should I ask the dealer to recheck the amount of refridgent, also I did not ask for the high and low pressures. I was thinking of putting an indicator light in dash to show when clutch disengages when driving, would it be possible to connect a warning light run off the clutch wiring circuit?. John

It should be fine to wire in a small bulb so that you can see when the compressor is energised.. The coil that Tim is referring to is the evaporator coil in the dash...

I'm speaking of the evaporator core itself. Is the condensation freezing on the core?

The evaporator will be the part that is located behind the glove box area, the coil is the part that gets cold next to the blower. Hope this helps!

Hi Jack/Tim,
Have not yet checked to see if coil is freezing up, but can tell you that when I go on a run water runs out through the drain pipe,as soon as I stop is this a indication that the coil is not freezing up ?Also as mentioned I have fitted a warning light into the compressor clutch circuit. I have come back from a 160 Km run on motorway driving and find the clutch will disengage now and then,I guess that it is engaged about 90% of the time with a ambient temp 34C (80F) is this normal.I must say I am delighted with the AMA kit that I fitted to my Suzuki 1992 Vitara ( known in the US as I sidekick) As I live in Spain I had to pay freight,duty,port cost,shippers costs,and Spanish IVA at 16% of total (similar to your sales tax). The total cost being about 2400$ so you see this turned out to be expensive, it was worth the cost to me as I could not find a system outside the US. I could have gone down the route and looked for a used system but did not want any problems that might have come from a second hand unit.One point I will make is that AMA are not export orientated and found it very hard to purchase from them. I have dealt with many States in the US and have never been asked to pay a sales tax but as I have now found out from your tax authorities in Arizona this is one of a very few States that impose this tax(TPT). To sum up system fitted perfectly and well engineered, I would like to recommend AMA here in Spain and in the UK, but feel that your company are only interested selling within the U.S.,which I can understand as you have such a large potential domestic market. Look forward to your reply on compressor clutch problem.Great forum
John

Well it sounds like the system is working well for you. the system will not cycle off till the coil temps reach about 36deg F. about 43deg F out the vents.

Hi Jack, thanks for your reply am happy that the system is working OK will check temp at vents also thanks to karl & Tim who also gave me advice.
