190E heater fuse blowing

[johntom]

Hi
i've just bought a 190e, 1991 2.0 auto. When I tried the heater blower (on max) it seem to work for a second then stop. When I checked the fuse box the 16a (fuse no'1) had blown, but someone had stuck a paper clip in!. Thinking it was a bad connection I replaced it with a new 16A. When I tried the heater it ran at max for a few seconds, then blew. How do i solve this, Any ideas?

You will need to take the blower unit out and maybe lubricate the bearings.
the comutators do wear, see what its like when you take it out.

Hi
thanks for the reply, do i remove the blower unit from the bulkhead side or is it under dash?
thanks Johntom

it's under the bulkhead/wiper assembley...not a easy job to do ...

As 190e nut says it is a hard job, are the wires easy to get to so that a test could be done in the car, or is the ressistor pack stopping access.

Hi
thanks for the reply. I had a look tonight, but couldn't get the cover off from behind the bulk head !.How would you test it in the car?. The heater works fine on 1,11,111, (although very little towards the screen) it blows on max after about 2 seconds.
thanks Johntom

to test on the car you need to access the live wire that comes from the ressistor pack to the motor (the other one is ground)this wire must be taken off the ressistor pack and join this up to a battery with an ammeter in serries to see the consuption.

Its not that bad; look for "190 blower knacked"

Two things make it easier and possible: get the bonnet vertical and loosen the middle bulkhead panel and pull this toward the radiator.
