I have been having trouble with my rear window defogger grids. They keep burning out and repairing them is very tedious and the repairs lately have not lasted for more than a couple cyclings of the defogger. Is there an electric heated defroster blower on the market that works good enough to make it worthwhile to use? I bought one of these fan and heating element type ones years ago, and it barely cleared a very small area of the rear window. ---

If you really want to “fix” it, replace the rear window with the built in defroster. It may not be cheap. ---

Check the connections to the defogger itself. One is power, the other is ground. Make sure that both connections are tight, and make sure that you have good ground. A bad ground could very well cause the problems you are havign. ---

A bad ground would deliver less power to the defroster, which would not burn it out. Is the an addon defroster or OEM? ---

OEM. I didn’t think you can buy aftermarket defogger grid kits anymore, I haven’t see them in stores or catalogs lately. But what about the heater/fan units that mount on the rear deck and plug into the lighter socket, are there any good ones, if they are still sold?
