Volvo S70 (1998 non-turbo medel) : AC is not working

[K B]

Hello Volvo experts,

AC is not working all the sudden - It worked couple of weeks ago.

So, I did the following test.

First, I check the AC pressure(where the cap says "Max 6 N.m) by pressing the the AC valve. Result: I got high pressure gas and yellow liquid on the cloth.

Secondly, I turn on the AC and checked if the compressor is working. Here, I noticed an interested behavior. The compressor is turning on for 1 sec and truned-off suddenly. This happening again and again with quite loud "click/tick" noice until I turned off the AC.

I'm planing to buy a OBD-II reader to see if that help. But, it would be greatly appreciated if anyone could pin point the problem for me. Many thanks.

Your compressor was cycling too fast. In most cases, that is a sign of low on charge. Get it checked out and recharged if needed at your local shop.
