nagcacrack ba ang windshield?

[turtleman]

nagcacrack po ba ang windshield due to changes in temperature? kunwari po, nakabilad sa araw ang kotse tapos nakatapat sa windshield iyong aircon..magcacrack po kaya ito?

[OTEP]

Generally no. But there are also external factors like weakened glass (age, etc.), chassis flex, and other factors.

Or maybe you have the hottest windshield and the coldest a/c. :D

Probably not even that. Here in Arizona, We'd have the A/C at 3/4 maximum with temperature inside the car an estimated 75F/24C (so cold sometimes we have to turn it down to 1/4) while outside, it's almost 120F/49C.

It'll have to take something solid like direct hit from a pebble to crack a windshield.

Yes, but in colder places.

When I wake up on frosty mornings, I usually see people who are

1 - too lazy to scrape their windshield/windows, or
2 - too cheap to buy a can/bottle of de-icer, and
3 - stupid enough to pour warm/boiling water on it.

Windshields can crack if you do #3. I know a few who learned their lesson the hard way

is the A/C directed at the windshield?

Unless you expose them to temperature differentials that large, the shouldn't crack... actually, even with the hot water in icy conditions, I'd bet newer ones would survive.

If the windshield will crack at all, it'll be due to chassis damage or flex, where the body is not perfectly aligned to the windshield anymore.

There is the odd windshield, though, that'll suddenly shatter for no reason. Honda had an issue with these in the 80's, I think.

Hahah, know a couple of dorm-mates who did this before hehe.

Saw this happen sa Gemini ng friend ko din, mga 60kph takbo dati (early 90s) sa SLEX and for no reason (walang tumama), nagcrack ang shatter nalang (tempered).

[bajumbo]

sobrang vibrations while running?

[OTEP]

Pwede din kapag nalubak, mag-flex yung frame ng windshield. Kung mahina na ang salamin, Crack! hehehe.

[vhenok]

happened din to me while cruising down NLEX on my Charade...for no apparent reason bigla na lang crack ung windshield ko...stop ako...then unti unti kumakalat ung cracks until bumigay.

AFAIK, a/c vents are not directed towards the windshield unless you enable the airflow indicating to that position. Yung nasa ibabaw ng dashboard.
