New Windscreen = Broken Wipers

Hi there,

Had a new windscreen fitted to our Smax, Autoglass via insurance as the old original had a crack from the perimeter that had slowly grown to around 10cm over the past 12 months.

Loads of the heating elements had failed on the old one so with the recent cold snap it was nice to have a full set of working elements to clear the new windscreen.

However, the rain sensing wipers are now pretty much useless. Even on the most sensitive mode they do not clear the glass before you cannot see, I once just left it for 1+ minute in very heavy rain and it did eventually wipe, at highest sensitivity.

I called Autoglass and a technician came out, sprayed the windscreen with a spray bottle, wipers worked so he didn't do anything else and left.

Next time out driving in rain, same issue.

A friendly neighbour works for Auto Windscreens so had a word with him, he confirmed what I had read online and that they probably reused the old gel pack so got replaced this for me. Sprayed the screen and it worked. Commented that the gel pack he removed looked good and had been replaced though.

Next time out driving in rain, same issue. This time passenger videoed it so at least have something to show the tech, if it comes to that.

My current considerations are:

Aftermarket glass is causing some weird issue?

The sensor is broken?

The sensor requires calibrating? Should such process exist?

Disconnect the sensor, which apparently reverts the wiper control to regular intermittent and live with it? Seems a bit of a naff fix given it worked perfectly with the original windscreen.

If resolving myself isn't too expensive in parts or time consuming I'd prefer to do this than go through the Autoglass process again. If the sensor is hundreds of pounds then makes sense to go down that route.

Has anybody had a similar experience? How did you resolve?

TIA.

Aftermarket glass is garbage. On my Fiesta Zetec S the heating element was about 70% what the OEM stuff was.
 
When i get screens replaced, I ask for OEM glass. NOT pattern glass.

The problem with this is that most insurers will say 'We don't care' when you ask this.

I wouldn't mind so much if you could pay an additional premium to guarantee OEM glass but the industry appears to have made a choice on our behalf that we'd rather pay 35 pence a year less for insurance than have a quality screen fitted.

I have never had a pattern screen last anything like as long as an OEM screen. I don't know if this is just co-incidence but the OEM glass always seems to last years and years but it seem to pick up chips within 12 months of a pattern screen being fitted.
 
When AutoGlass came to repair a chip in my E43 the chap did say you can ask specifically for OEM and pay the difference yourself.
 
I had the choice of Autoglass screen or pay £400 odd quid for OEM so went Autoglass and must say it's been perfect.

Ford Focus -heater and wiper sensor work fine.
 
Had one done for a 3 series about 7 years ago, local Cambridge company provided a demanded OEM screen, ~£150 fitted, in works car park
Screen needed replacing because it was scratched from wipers, but had inadvertently cracked it when I let naked wiper arm fall against it,
payed myself because I cracked it, I speculated they put a large premium on for any insurance jobs, although was getting some big quotes from nationals I recollect.
