I think my rear window defroster has gone bad...if that is possible. At one point in time it would practically burn the moisture off of the window, now this morning in the it was barely doing anything..Any ideas? I've already checked to make sure the wiring was connected..TIA

 

If I'm not mistaken there's a timer built into the defrost switch that can over tiem stop working right (the on/off cycles get out of whack) and I'm sure that over time the defrost elements themselves on the window can stop working right, either too much resistance or a break in the circuit somewhere

 

Yea, my defroster will turn off by itself after having it on not too long at all. And I always have to keep turning it back on, gets really anoying. How in the world could I go about fixing it?

 

it comes on...it just takes forever to defrost the window..it seems to run the same amount of time it always has...it is just becoming less effective...i hope solving the problem doesn't mean replacing the glass

 

Try replacing the 30 amp breaker with a 30 amp fuse. It has worked for a lot of folks.

 

Grid testing info.

 

i'll take a look at it to make sure that everything is in tact....what would the breaker to fuse conversion require? TIA

 

A fuse...
That post was meant for 96ZCamaro's problem, not yours.
You remove the breaker and install the fuse in it's place.

 

gotcha...i guess i just gotta get out the chamois every morning

 

Will changing to a 30amp fuse affect any wiring or any other electrical items?

 

No.

 

I replaced the breaker with a 30amp fuse. The fuse blew within 2-3 mins. Is this an issue with the rear window defroster lines?

 

Could be. Something is causing too much current draw.
