The rear defogger must have two connections. It works off of DC current and needs a positive connection and a negative connection in order for the electrons to flow and create heat. There are some kits out there which might help you to get this fixed, but I've never used them and don't know their voracity. They basically re-link the broken side back into the ...

Well, there are some downsides. First, most cars turn it off automatically so the manufacturer doesn't think you should leave it on all the time. The way the defroster works, it's a grid of thin conductive silver ceramic lines that are painted onto the rear window, before being baked on at high heat. In operation it is a high current device that on average ...

Mirror and window heaters will not feel warm to your touch. The heater only heats the glass to slightly above freezing, which is sufficient to melt snow and ice. An empirical test whether or not the mirror and window heaters are working is to start the car, enable the rear window heater, and leave the car idling for a few minutes. Ideally, if you can let ...

Your question about being plugged into a charger is an important one. Most (all?) EVs today permit "pre-climate" control in which the vehicle remains connected to the EVSE and will run the air conditioner or heater to accomplish the desired result without draining the traction battery. We had a pair of 200x Rav4EVs which did this, so it's not a ...

The most convenient solutions are an electric engine block heater (as @mikes mentioned) or a petrol/diesel powered stationary heater. The latter is expensive, but generally more powerful than a block heater. Putting a space heater inside the car interior is possible, but has some drawbacks. Running an extension cord into the car is one: I'd recommend to ...

I've seen GMs that burn up/melt the passenger side relay block/trunk fuse panel. Due to the rear defroster being run constantly.

In addition to Solar Mike's answer, I'd suggest the Permatex Complete Rear Window Defogger Repair Kit. It has worked well for me in the past.

You could have a block heater installed. A block heater is a heating element that runs on household current. It is usually installed either in place of a freeze plug or in line of a large radiator hose. The power cord will then be run through the grill for access. The heater warms the coolant in the engine block and radiator. You could theoretically switch ...

If it is the thin “wires” on the glass then I have had success in the past with silver conductive paint. You have to find the breaks and clean them back to metal - I used a razor or scapel but be careful they are very very thin. Then mask each side and coat over the break. Follow the instructions for the paint.. remove the masking and test only when dry. ...

In response to the suggestions given here, I was going to throw some snow on the mirror face and see if it melted. Tonight, however, the weather cooperated and coated the mirror with freezing rain. I drove for 20 minutes, the first 10 on the highway. The ice melted away. On the driver side, however, it's not ideal. There's a margin around the lower and ...

Yes, defrosting works like with any vehicle - it just uses the battery instead of gas. With the Teslas this happens automatically. If you ask it to start from the app and the outside temps are low, it'll defrost, preheat seats and steering wheel. https://insideevs.com/tesla-updates-mobile-app-cold-weather-features/

So, is the supply getting to the terminal on the window? If not then the cable can be broken in the area of the hinge... Is there a ground connection? same issue with broken cable. The third possibility is that all the thin elements have been damaged if the two things above are ok. One way to check is to use a test lamp or multimeter and check to see if ...

Handbrake cables and many other cables can trap water over time. While your handbrake cable had an obvious cause, it is still difficult to get ALL the moisture out, copious use of WD40 or equivalent, moving or removing the cable to get rid of any low points to allow the droplets to collect and drain are possible. Replacing the cable is also an option. Had ...

I did this once, it depends on how thick and wide the original lines are. I cut back each side to well-stuck lines (does not work trying to join to loose lines), then masked the section that needed replacing, the idea is to get the masked gap to match - if it goes thicker it shows up... Then I used 3 or 4 coats to build up the section. Whatever you do don’...

A tube heater (first hit on google) on the dashboard does a good job. You can either run a suitable extension through the door seal (I suggest the bottom in case of rain/snow/meltwater, and the driver's door so you don't forget about it). The tube shouldn't really touch the plastic of the dash, but in my Transit the end caps are the only points of contact ...

You're overthinking this. Just: start the car turn the heater on lock the car with the keyfob (engine and heater still running) go back inside your home and have a coffee for 20 minutes

If you leave it on while the engine is not running, then you will quickly flatten the battery. Other than that, it will do no harm leaving it on. It will of course cause a small increase in fuel consumption.

As others have stated, it is meant to operate this way. That being said, many of the vehicle specific online forums talk about how to disable it, to allow manual control. Searching, I didn't find a way to do that for your generation Voyager. For the prior generation, it was possible to disassemble and modify the HVAC control. No one has reported a way to ...
