NIssan Tiida A/C Problem

[morff14]

Salam,

So my Nissan Tiida's A/C is giving the following problems:

Upon cold start, it works fine for about 15 20 minutes ( or more if I keep driving at a high speed without stopping). But as soon as I slow down due to a traffic jam or at a traffic signal, it stops throwing out cold air (as if the compressor stopped working). Then I have to switch off the car (ignition off) and then back on for the AC to kick back in. Only turning the AC off and back on does not help. But soon, the AC trips out again. and I have to follow the same drill again. This usually continues untill I'm out of the traffic jam and have picked up some speed.

So basically, the AC trips and does not come back - occasionally.

It may appear obvious that is has to do with slow speed ( low compressor RPM) but I don't think so. When it's working alright, it's freezing cold even at idle. Gas pressure is good.

Any ideas what might be causing this? Looks to me like an electric issue.

Thanks,

It was an electrical issue. The switch that controls the "trip" mechanism had rust in it. So after tripping, it would not pass current. Cleaning the switch with warm water and then using WD-40 spray fixed it for me.

I'm having this problem now , where can I find the switch ?

HELP PLEASE !!

Hey. In my case, it turned out it wasn't the switch. It was the AC Compressor's clutch. The assembly inside the clutch would "heat up" and intermittently not engage back after tripping. The switch just reset the connection to the clutch so it would world again and hence I thought switch.

I got the clutch services (which some mechanics told me isn't a good idea, replace the whole compressor). Few months later, the compressor started making noise so I got the whole thing replaced.

Get it checked by a mechanic and if he points it to the compressor clutch, then get the compressor replaced.

Good luck

Well I sorted that part out & it still not coming in after tripping

Guess I'll be needing a compressor then

Good luck. Where are you based? Be informed that the process of changing compressor will require refilling the refrigerant gas.

Let me know how it works.
