Hi
How you doing.
Wanted to tell you guys how my interior AC fan has died down.
The way it has died down is like this.
First the speed 1 & 2 were gone at this time speed 3 & 4 were ok though reduced a little. But after about 2 weeks the fan stopped completely. The mechanics says that blower motor is gone. Is it likely. The problem is that in India its really very hard to trust car repairing shops. Can I do some checks to make sure that this may be due to some minor electrical issues. Also the heater is not working as well. I have got the fuse box checked. No problems with the fuse box.
thanks in advance.

The first thing I would recommend is to check, at the motor, if there is power present. If there is, the motor is bad. However, your description sounds like the resister went bad. Please keep in mind, if the motor is drawing too many amps because it is going bad, it will burn out the resister.

Hi Jacob
Thnx a ton. I will be grateful to know why would a motor will draw more current when its going bad. Also would be nice to know how much register and blower motor should cost individually. Thnx in advance.

When the brushes or armature in an electric motor wear, they require more amps to function. As far as price, I don't have access for this model vehicle.

Hi
As the syncromesh of my Opel Astra 1.6 1997 is geting old I am thinking of using RPM matching while downshifting. In India we have to downship very often because of constant traffic jams. For example say I am in 2nd gear and my tachometer is reading 2000 rpm and car is moving at 30km/hr speed. Now I know that traffic is slowing down and its better I change to 1st gear ASAP. Now say if I press the clutch down and put the gear shifting lever in neutral position for about a few seconds. Do you think that syncromesh will still be moving at 1000 rpm assuming that the 2nd gear ratio of 2:1. If synchomesh is always moving at the speed of the wheel then I will have to rev the engine to 3000 rmp after releasing the clutch because I know that 30km/hr is achieves at 3000 rpm in 1st gear. But if puting the car in neutral make the syncromesh loose rpm then I think its should be easy and safe to try to put the gear lever in 1st gear position when clutch is pressed for a few seconds and gear lever is neutral at the same time. Please advise how to change the gear from 2nd to first in safe way so that the life of the syncromesh is extended. My biggest problem is actually downshifting from 3rd to 2nd. The syncro has become very tight from 3rd to 2nd.
Thanks in advance
