today i noticed while driving my 99 disco I, the air conditioning abruptly shut down. i turned fan off and on again and it restarted. this happened twice today. maybe unrelated but my check engine light was on for 2 days then went out. it was not on when the a/c did it's new trick! temp guage is is normal....

 

Mine has been doing the same thing for months and I haven't been able to figure it out. Mine does appear to be heat related however. Good luck. I will be following this thread closely to see what you find out.

 

Is your a/c system full of R-134a?
You can check this yourself with a DIY a/c recharge kit.

 

is the A/c itself quitting or is the fan stopping intermittently ?

 

thanks! we are in a heatwave here in phila!

 

will check that! thanks!

 

good question....i'll pay attention if it happens again.

 

My 97 the fan would cut out at random times on heat or AC. It never happened enough to bother troubleshooting but I was thinking either a loose connection or a failing blower motor.

Try to pay attention to whether you hit a bump or anything out of the ordinary when it happens. That should give a clue to what's causing the problem. If it cuts out after you hit a bump I'd think loose connection somewhere in the system.

 

I would bet its a bad switch on the dash. Mine was doing the same thing and I got mad and broke the switch then I replaced with a new one no problems of it shutting off since

 

Old thread same issue

Last few days blower on 4 a/c on

Blower cuts out and a/c light turns off then both come back on, only affects front a/c blower

Bad fan switch?
