2 problems in my Zen

Hello all,

As most of you know that I drive a 2005 registered Zen Lxi. I am facing this weird problem with regards to the A/C. Despite it being at full speed of the blower, its not cooling enough. What could be the reason?

Secondly, Of late I have been noticing that the fan of the car in the engine compartment is still on after I come from a short trip for about 10-15 mins min even after I switch off the engine and take the keys out.

I find this strange and am sure something is wrong but no signs in the dials/speedometer.

Get the Gas checked for the AC. Normally, a refill will cost you around 800-1000 and ask the person to check for any leaks!

It's definitely a problem with the Fuse.
Even I faced the same problem once when the fan started running on it's own when the car was parked for more than 10 hours. Luckily I noticed it before the battery was drained.
It was a blown fuse and the replacement was for around 150 bucks.

Location of fuse: Somewhere below the coolant tank!

Reagarding the first problem, get the refrigerant gas level checked in your AC. Should not cost more than 1000.

The second problem could be due to the Fuse, as Pulsar56 pointed out. Even I faced the same problem in our Indica. However, it could also be because of the AC itself. Might be a case where the engine is overheating as the compressor is having to work hard due to low refrigerant levels.

It is not normal when it keeps running after the ignition is turned off and the key is removed!

It's a 5 minute job to replace the fuse amtak, head to a garage immediately. unless you want to drain the battery with the fan running when the car is parked!

when you switch of the ignetion if the car is still hot the thermostat will control the fan.
maybe i am wrong.

AC gas refilling would cost about 1k from local shop, and about 2k from M.A.S.S.
I would recommend going for M.A.S.S since the quality of gas they use is much better and it lasts long too.

Well, My suggestion was based on what happened in my car! When you turn off the ignition, there should not be any power going to the fan even if the thermostat senses that your radiator is hot!

In my case, it was a conked fuse connecting to the fan which was sending power to the fan and it had started running when the engine was completely cool irrespective of the thermostat!

Peace!

ive had this strange problem in my zen.its happened just twice or thrice.

the car starts up and just after a few meters of driving the car goes off and then it just doesnt start for a few minutes.it cranks up but just doesn fire.(hope you get what i mean)

the only way out was crank it a number of times and finally it starts.some times it does start up but immediately goes of.
EDIT its a 98 carb.

Looks like the fuel pump / fuel filter is the culprit.
