How to Increase Blower Speed?

mercedised · 8th May 2010, 20:48

Hello Friends,

Summer has already started, and the blower speeds of my TCIC SAFARI and INDICA 1999 are too much slow that sometime i have to put the AC to off and roll down the windows. It's really irritating to drive without AC in hot traffic. Please anyone suggest a method of Increasing blower speed from the stock set-up?

I have got all of my wirings, blower motor's checked and the company guys tell that everything is fine and me too have experienced this with other Safari's\Indica's. Basically, I feel that the blower speeds of stock set-up are not UPto-the mark.

Thanks.

With engine running and accessories like music system ON, check the battery voltage, if its below 13v then blower will not run at its full speed. Also check for any air leaks from dashboard.

If all is fine then maybe we can take out the blower motor and fit a higher RPM motor there? Never seen anyone doing/suggested here in forum but it might be possible.

Get the blower motor checked for Bush problems
or there may be something stuck on rotor to prevent it from attaining full speed.

Get your AC filter cleaned...that gives the biggest benefit & is almost free!

Thanks guys.
Blower motor seems alright, already checked. Ya! AC filter cleaning will be tried on my next visit to SC. For sure.

Perhaps its time to clean them?

Do the Safari and the Indica have ac filters?As far as I know,they don't.

Oops! I meant clean the blower! You are right vigsom, dont think there is any A/c filter

Hello,

Goto a good AC mechanic and ask him to remove your entire DashBoard and clean your Blower Fan & Evaporator (which is inside the DashBoard).
Due to Lot of Dust accumulation, the Fan Speed (due to Dust weight) may have reduced. Also due ot dust accumulation, the effciency of Evaporator must have reduces drastically. Its better if you present in garage during these activites, so that you can see as whats happening. (and most of time, these mechanics don't clean it up, unless you are watching over their shoulder).
This should increase your Cooling drastically.

I have done this in my Sierra and cooling is too good now.

Maybe it's your resistors, these affect are what control your speed settings, if it's working the same as before, you could try a bigger blower from a different car, fitting it could be trouble though.

Maybe you just need to get the AC gas refilled again.

AFAIK, the AC on the Tata Indica is one of the best Chillers in its class. I have an Indica DLS and I never can go above the 3rd position on the blower with AC on.

Since you feel that is the issue on other cars too, did you compare with a new car?

I have got a cut-out\relay fitted, now the blower speed has increased. But, only marginally?:(

After all these cleaning and checking things and not yet satisfied with the results, I think you need to check the blower motor next.
If there is a possibility for you to swap a blower motor from a relatively newer vehicle (Safari/Indica) and check, you can indeed confirm if its the problem with the motor itself.
